    Photoshop CS5 Users - Performance Checks Wanted From You

    Noel Carboni Community Member

      A few days ago, while discussing various system configurations in answer to posts asking about what's best in new computers, it occurred to me that while we all know our own computers pretty well, it's practically impossible, without a whole bunch of different systems to work with on hand, to judge what system works best with Photoshop.  Is more cores better?  A superduper video card?  Huge RAM?

       

      Got a few minutes?

       

      I propose we try a few "real world" things with Photoshop CS5 on our systems and report how quickly/interactively it does them, as well as our system configurations, in an attempt to understand what works best.  This isn't a "one upsmanship" contest, but just a poll to see what systems really blaze through Photoshop work.

       

      Let's try to keep the list of "some things" fairly small, so we can all easily try them.  And the timing isn't too critical... Use a stopwatch if you can, or just watch the second hand on your watch or a clock and guestimate the timing to the nearest second.

       

      List these things about your system:

       

      A. Your architecture (PC / Mac) and what OS you're running.

      B.  Number of processors / processor models / GHz speed.

      C.  RAM size, speed.

      D.  Hard drives (OS, Photo storage, Photoshop scratch), their sizes and speeds.

      E.  Video card (model, graphics memory on board).

      F.  Your Photoshop Preferences settings - Amount of RAM you've allotted Photoshop, whether you have OpenGL enabled, scratch disk allocations.

       

      Here are the things I think might be useful for multiple people to try and let us know the time it takes:

       

      1.  Cold start Photoshop, from where it is not running.  How long does this take from start to everything on the screen painted and ready to work?  Do it several times.  If you use both the 32 bit version and the 64 bit version, see if there's a difference in startup time for each.  This test represents how long you'll have to wait when inspiration hits you and before you can start working.

       

      NewTestImage.jpg

       

       

      2. Create a big, new RGB image, 10000 x 8000 pixels in size, 16 bits/channel.  Time how long it takes to File - Save As a .PSD in the location you often save files.  Make sure you're set for Maximum Compatibility for saving PSDs.  This gives your disk subsystem a bit of a workout.

       

      SaveAsTiming.jpg

       

       

      3. Choose a round brush, set the Hardness to 0% (i.e., as fuzzy as possible), Spacing down to 10%, disable all the dynamics, and set the foreground color to something other than the background color of your image so you can see your strokes.  How do brush strokes on your screen keep up with you interactively under each of the following conditions?  If not, how long does it seem to take to catch up to where you just painted?  Does it follow everywhere you moved your mouse, or at some point start to skip places where your mouse went if you paint quickly?

       

      3a. Brush Size 100px.

      3b. Brush Size 200px.

      3c. Brush Size 300px.

      3d. Brush Size 400px.

      3e. Brush Size 600px.

      3f. Brush Size 1000px.

      3g. How big does the Brush Size have to be at 10% spacing and 0% hardness before it gets too laggy to be practically useful without slowing your strokes down hugely.

       

      BrushStrokes.jpg

       

       

      4.  Filter - Blur - Lens Blur.  Change all the controls to 0 then the Radius to 20 pixels and time how long it takes to fill the preview with the image (all checkerboard gone).  You can cancel the Blur filter after the display is filled.  This is a single-threaded plug-in.

       

      LensBlurTiming.jpg

       

       

      5.  How long does it take to complete an Unsharp Mask on the image you've painted, using a setting of 250% amount, 250.0 pixel radius, 0 levels?  Time how long it takes after hitting the OK button to Photoshop being ready for you to do something else.  This is a multi-threaded plug-in.

       

      UnsharpMaskTiming.jpg

      You can go ahead and close the above image after the Unsharp Mask operation.

       

       

      6. How long does it take to convert a Canon EOS 7D and a Nikon D7000 image with default settings, between hitting the [Open] button in Camera Raw and the image appearing in Photoshop to be ready to edit?  You can find raw files online to try with.  This is where I got the ones I tried:

      http://www.imaging-resource.com/PRODS/D7000/D7000FARI00100.NEF.HTM

       

       

      Please don't be shy about posting your results. 

       

      Your computer is what it is and there's NOTHING to be ashamed of.  Some are going to be faster than others at different things, and I think it will be really enlightening to see how the different system architectures handle these operations.  It can be a more or less objective way to see what architectures really do give great Photoshop performance.  Then when people ask "what's the best architecture" to get to run Photoshop, we can respond with more confidence and point them to this thread.

       

      I'll post my own results in a bit.

       

      Thanks!

          Here's my system in a nutshell:

           

          A.  Dell Precision T5400 PC Workstation running Windows 7 x64 Ultimate.  I have two 1600 x 1200 pixel Dell 2001FP display monitors.

           

          B.  2 Intel Xeon X5460 3.16 GHz processors with 12M cache and 4 cores each (8 cores total in the system).

           

          C.  16 GB of 1333 MHz DDR2 RAM in 8 x 2 GB DIMMs, which provides quad channel access.

           

          D.  Drive C: is 2 x 1 TB Western Digital RE4 SATA drives in RAID 0, Drive D: is a Hitachi 1 TB SATA drive.  All are 7200 RPM, and using SATA2 connections.

           

          E.  Video card is ATI Radeon HD 5670 with 1 GB GDDR5 memory, running the ATI Catalyst 11.12 driver.

           

          F.  Photoshop 32 bit set to use 100% RAM (3255 MB), OpenGL disabled.  Photoshop 64 bit limited at 95% RAM (13962 MB), OpenGL enabled, Normal mode.

           

          Here are my test results:

           


          1.  Photoshop 32 bit took 10 seconds initially to come up, then after closing it it took between 4 and 5 seconds to come up on subsequent cold starts.

               Photoshop 64 bit took 6 seconds to come up at first, then after closing it it took about 3 seconds to come up on subsequent cold starts.

           


          2.  File - Save As - PSD an 80 megapixel 16 bits/channel image took 2 seconds.  File was 468 MB on disk.  Timing was the same in both 32 and 64 bit Photoshop.

           


          3.  Painting interactivity with various brushes was good up to the larger sizes, where it started to get laggy:

           

          Photoshop CS5 32 bit:

           

          3a-d: Brush strokes are perfectly Interactive at 100px through 400px with any speed strokes.

           

          3e: Started to notice a slight delay at 600px. Stroke across entire image follows the cursor cleanly, but a small fraction of a second later.

           

          3f. Delay noticeably longer at 1000px, probably 1/3 to 1/2 second. Quick curvy strokes result in loss of some of the positions the mouse traversed, the resultant stroke becoming straight between points.  Still quite usable for painting if the mouse is moved a little bit more slowly.

           

          3g. At 2500px the brush paints in noticeable jumps, a small fraction of a second apart. Somewhat usable but the mouse would have to be moved extremely slowly.  Practically unusable for painting.

           

          Photoshop CS5 64 bit (slightly poorer performance than in 32 bit Photoshop, perhaps because of OpenGL setting difference):

           

          3a-c: Brush strokes perfectly Interactive at 100px through 300px.

           

          3d: Started to notice a slight delay noticed at 400px. Stroke on screen follows the cursor cleanly, but a small fraction of a second later.

           

          3e. Delay noticeably longer at 600px, probably 1/3 to 1/2 second. Quick curvy strokes lose some of the positions the mouse traversed, becoming vectored.  Possibly usable for painting but only if the mouse is moved very slowly.

           

          3f. A quick stroke across the image at 1000px size results in it taking 1 second or more to catch up.  Probably unusable for any kind of painting.

           

          3g. At 2500px the brush paints in noticeable jumps, about 1/4 second apart. Possibly usable for spot retouching but the mouse would have to be just single-clicked.  Completely unusable for painting.

           


          4.  Lens Blur, with More Accurate setting and 20 px Radius, took the following times to fill the preview display of the filter, and (per Task Manager) appeared to be using only one core:

           

          32 Bit Photoshop:  2 minutes 5 seconds (125 seconds).

          64 Bit Photoshop:  1 minute 20 seconds (80 seconds).

           


          5.  Filter - Sharpen - Unsharp Mask, with 250% Amount and 250.0 px Radius took the following times to complete after pressing OK:

           

          32 Bit Photoshop: 9 seconds.

          64 Bit Photoshop:  12 seconds.

           


          6.  Opening raw images took the following times:

           

          32 Bit Photoshop: Canon 7D Image: 3.8 seconds  ;  Nikon D7000 Image: 1.4 seconds

          64 Bit Photoshop: Canon 7D Image: 2.5 seconds  ;  Nikon D7000 Image: 1.5 seconds

           


           

          Looking forward to seeing your results.

            So this is how PC users spend their time? Good luck with that.

              Wow, you're wanting to turn this into a Mac vs. PC thing?   Can we assume your Mac performs dismally, then?  ;)

                  It does look a wee bit of a hassle Noel.  I did wonder if there was too much chance of variables and user error making the results unsafe as well.    How did you measure the times BTW?

                 

                I had a go at the brush thing, but I was able to use a max sized 2500 pixel brush with vertually no lag.   I'll try that lens blur thing seeing as you have gone to so much trouble.

                 

                Sorry I lied about the brush size.  I had used a fully hard brush, (but that's par for the course with Windows users )

                 

                After reading the instructions properly and using a (Mac like) fully soft 1000 pixel brush,  I could write the 1000 on the image with just a tiny bit of lag, but if I did a (very) vigorous scribble the brush lagged by about 0.5 seconds by the end of it.

                  A. I have a custim built PC running windows 7 64bit and featuring an i7 950 running at the stock speed of 3.04 Ghz. 4 cores 8 threads.

                  B. 6 GB DDR3 RAM running at 2,000 Mhz.

                  C. One hetachi 500GB 7200 RPM 3gb/s deskstar drive.

                  D. One hetachi 1TB 7200 RPM 6gb/s deskstar drive.

                  E. One 60GB SSD OCZ Agility 3 6gb/s (photoshop and windows are installed on this drive)

                  F. Nvidia 9800 GTX+ 512 MB

                  G. OpenGL disabled Photoshop allowed to use 3GB of RAM of 6GB

                   

                  1. Photoshop took 3 seconds to come up from a cold start.

                  2. Saving the 10000x8000 file as PSD took 2 seconds.

                  3. Brush sizes start to get laggy at 1,100px but at 1,000 and under it was fine.

                  4. lense blur took a good 8 seconds to come up in the window and to save took close to a minute.

                  5. The unsharp mask took 8 seconds to load after clicking ok.

                  6. cannon vs nikon they seemed to be the same as far as I could tell closer to 2 seconds.

                    Thanks for the results, guys.  Very informative!  Both of you have quite powerful systems, that's good info for anyone looking to get a new system.

                     

                    It seems that painting gets laggy with brushes greater than 1000 pixels.  Probably very few people paint with 1000+ pixel brushes...  Perhaps I should have suggested using the Mixer Brush.  In my experience it doesn't take such a large size to slow that one down.

                     

                    Trevor, I used a regular old mechanical stopwatch from last century.   

                     

                    I really would like to hear from Mac users as well...  How do people know which Mac to choose?  I mean, there's a fairly small product line, but I'm sure they don't ALL work equally well.

                      Hey Trevor,

                       

                      By the way, could you please try the Lens Blur feature on the 80 MP 16 bits/channel document on your powerful system? That would give a reading of how much throughput a modern Intel i7 provides with single threaded operations.

                        Update:  ATI Catalyst 12.1 drivers have made an improvement of painting interactivity for me using the 64 bit Photoshop.

                          Hi, Noel!

                          There might be a need for further information: is disable flate compression plug-in installed or not? http://kb2.adobe.com/cps/902/cpsid_90248.html

                           

                          Also, the preferences>Performance History and Cache should be stated (tall and thin, or large and flat, default) as well as the number of history states.

                           

                          The size, and presence or not of layer thumbnails, of the info or navigator panel could be a parameter that can influence the results.

                           

                          (This could also become a how to optimize Photoshop for certain tasks thread)

                                Thanks for the feedback so far, guys.  I haven't disabled compression in my system, yet the 80 megapixel 16 bit pure white PSD file took nearly half a gigabyte to save.  As far as the other things, especially painting speed, I don't think settings will affect them that much.

                                 

                                And no harm no foul re: Mac vs. PC.

                                 

                                So let's have some test results, guys!  How are people supposed to know what to expect with Photoshop on their prospective new systems if folks don't list what kinds of performance they see on current systems?

                                  First, I would suggest some standard benchmark tool so that we know where the system stands with respect to a common group of tests not formulated on the spot. I don't recall ever running a validation on a system without such standardization. Even then, we had to run the tests at least 5 times and average the result, or even compare mean against average, with a larger suite of tests.

                                   

                                  With a common mobo, cpu, video card and ram, the range between individual setups is ascertained and  plugged into the calculations.

                                   

                                  I realize we won't go quite that far, but seriously, what the best individual system does here will only be  a starting point. For instance, I can overclock. I can mess with memory timing and latencies. For some PS operations, I'll see a difference, others, not.

                                   

                                  A true test will hold everything constant then change one parameter. Tedious and boring, but oh so informative!

                                    Noel we used to have an OK Photoshop benchmark tool over on the flickr Photoshop Support Group but results table has been broken for several weeks now.  I have just PM'd the guy who started that thread and asked if he might get round to fixing it, but I have a feeling I am not the first person to ask, so I don't have high hopes.   The nice thing about this benchmark was that everyone used the same downloaded image, and it ran from a script, so there was limited user input, and the times were recorded by the computer - not that I have anything against your egg timer  stop watch.

                                      I get what you're saying, but even less than formal results would help highlight system differences.

                                       

                                      What are the possible outcomes? 

                                       

                                      1.  Most modern systems might provide similar performance - e.g., almost everyone could save a 500 MB file in a few seconds, paint acceptably well with a 1000 pixel brush, not wait too long on single-threaded filters...  If that were the case, then pretty much anyone who asks could be told:  Just get a modern system, it will perform well enough.

                                       

                                      -or-

                                       

                                      2.  Some particular kinds of systems (e.g., those with SSDs or hex core processors or 16 GB of RAM) might perform noticeably better.  That would be enlightening, and support advice being given to purchase these kinds of systems.

                                       

                                      Without even basic seat-of-the-pants measurements, we get no indication at all of what works and what doesn't.  Or maybe we really do have to get very accurate results in order to split hairs and see real differences, but I doubt that kind of discipline can be brought forth from a forum.

                                        It just seemed to me that a one click, no nonsense, script driven test is more likely to get people taking the trouble, and there were a fair number of systems on the results table before it broke.  I have already heard back from the guy behind it, and he is making moves to get it fixed.

                                          These kinds of tests are run at Anand Tech and Toms Hardware. Sufficient time to search these sites is an excellent way to get some good answers. They have the advantage of rigor which, if I were to sum up what I posted above, it would be one word: rigor.

                                           

                                          The one click script run setup to which you linked is one I would include in a checkout after building/buying a system and one that should give good feedback when tweaking.

                                           

                                          Passmark is another test I like to use. They also provide a rating system if you care to upload your results. You can also privately do your own comparisons by downloading test results for selected systems.

                                            Some of you have provided good, usable info:  What brush lag you see at various brush sizes.  THANK YOU.

                                             

                                            Some of you have avoided this.  I can only assume that you're either ashamed of your performance or couldn't follow my instructions.  Since I doubt the latter, aren't we more adult than this?  Please check your ego at the door - the computer you have is what it is - no one's going to laugh at you or lose respect for you if you say that your system, with your particular processors and video card, only allows you to paint with a 400 pixel brush before it starts to slow down.  Frankly I was hoping to hear that certain new systems with ABC processors and XYZ video cards could allow painting with a 2000 pixel brush.  THAT would be helpful, useful info as well - it would help us all choose our next new systems.

                                             

                                            It is USEFUL to know how systems are performing in the real world.

                                             

                                            On the chance my simple 6 steps above seem too daunting, should I start a new thread with even simpler instructions?  I think it would be telling to learn how the Mixer Brush performs on various systems.

                                              I'm not sure there is a simple linear relationship here.

                                               

                                              I just painted extensively with a 2500 px brush with no lag whatsoever. That is on a very modest system with an ATI 5750 video card and an i5 750 CPU. I'm sure the benchmarks are nothing to write home about.

                                               

                                              In fact I always steer away from the fastest bleeding edge. I want stability. I don't really care about speed, I care about the thing not crashing. I deliberately picked the modest i5 750 over the (then) much fancier i7's, because it was by then tried and tested as compatible with almost anything, and was known as a solid workhorse.

                                               

                                              The tortoise and the hare, you know?

                                                Dag, did you have hardness at 0% and spacing set to 10%?

                                                 

                                                Noel, that thing called real life got into my benchmarking attempts on my laptop.

                                                But let me second the request for changing a parameter at a time. Like we do with 64bits/32bits when using more than 4Gb of RAM. If somebody wants to send me an SSD, I'll be able to compare too

                                                RetouchArtists is also a very widely used Benchmarking script.

                                                  Funny, but the i5's and the i3's are derivatives from the i7 technology. You may have a processor that cannot pass i7 requirements and have only 2 cores activated.

                                                    OK, hardness at zero introduces a slight lag, perhaps 1/4 second. But nothing unworkable. Hardness at 100 is instantaneous.

                                                     

                                                    Spacing all the way down to 1% brings the delay up to perhaps a full second.

                                                     

                                                    But this is, as I said, 2500 pixels.

                                                     

                                                    I'm sure these numbers could turn ugly in an instant with a different video card driver, for instance. The thing is, I'm not sure it has all that much to do with specifications taken at face value. I believe it is more finding components and drivers that work well together.

                                                        I haven't gotten too far into the tests, as I don't use the brush for drawing only as an adjustment like Dodge, Burn etc.

                                                         

                                                        Nonetheless, here is some results.

                                                        Opening the 3 big picture 2 sec.

                                                        Painting with a 400 pix brush at specified hardness and spacing at 25% 1.4 sec to complete a swift stroke across a diagonal. At 1000pix, 10%, 4+ sec...useless.

                                                        Getting this far is much more than a few minutes! It is now 8 AM. I commenced this test about 6AM, with approx 1/2 hr for coffee, checking e-mails, arranging  dual screens to be useful to test and record, validating setup data etc.

                                                                    On the specified task : 10000 x 8000 pixel 16 bits/channel image, 2500px diameter round brush, hardness 0%, Spacing 10  I made a straight line path (pen tool) from corner to corner. I then commenced the timing by clicking on the stroke path icon and read the result when the stroking stopped. I used the second hand on the Windows 64 Vista  clock gadget for the measurement.

Will retest tomorrow, sorry for not reading the fine print...Back at my home system now and looking at delays in the 3-5 second range.

                                                                       

                                                                      Anyway, I re-read my post #19 and realize it perhaps came across as...gloating (is that the word)? I apologize for that, didn't mean to. I just honestly believe this has more to do with compatibility than anything else (the brush strokes at least).

                                                                       

                                                                      The thing with the i5 750 is that at that time it had been on the market for about 18 months. All the motherboards were ready for it, all the BIOS'es knew it inside out. The top-of-the-line iMacs had used it for a long time. It was old stuff.

                                                                       

                                                                      And I'm sure modern GPU's are more than fast enough to deal with 2500 pixel brushes. But we all know video card drivers can be less than optimal, or optimal in one configuration and not in others.

                                                                      • 32. Re: Photoshop CS5 Users - Performance Checks Wanted From You

I'll just be over here in the corner...

But on paper your system should be much faster than mine. So I do think I'm coming out of this with my head high after all. At the moment I only have 8GB RAM and 512 MB VRAM, and my quad-core CPU is slower than each of your two. I have DDR3, though, if that matters.

I still don't understand why it should take 2 seconds to save a 10000 x 8000, 16-bit flat file (psd). Here it takes a half second, and that's with an image on it (not pure white). No RAID, straight 7200 SATA2. 458 MB on disk.

                                                                                   

                                                                                  What's going on with these numbers?

                                                                                  • 38. Re: Photoshop CS5 Users - Performance Checks Wanted From You

                                                                                    You are counting too slowly?

                                                                                    D Fosse, are you by any chance running the Disable Flate Compression plug-in, as I linked earlier in the thread? From the file size, it does not seem so.

                                                                                    Compatibility on or off? (should not matter on a flat file)

                                                                                    • 39. Re: Photoshop CS5 Users - Performance Checks Wanted From You
