    Lightroom CC disgustingly slow - old issue, NEED ANSWERS

    romen cole

      Ok, before I begin my rant, here's my spec sheet...

       

      Mac Pro (Late 2013)

      El Capitan v.10.11.6

      3.5 GHz 6-Core Intel Xeon E5

      16 GB 1866 MHz DDR3 ECC

      DUAL AMD FirePro D500 3072 MB

      256GB SSD Internal Drive

      3x 512GB SSD Samsung Eternal Drives (non-RAID)

       

      I wanted to make sure it is already established that I am operating far beyond the "minimum system requirements". With these kinds of numbers, I should be able to manage the 3DFX for a motion feature film and not really skip a beat. I am a professional photographer and I shoot with full frame and medium format camera systems. Honestly, that is moot because I am seeing that bloody skinny wheel of death when dealing with the RAW files from both cameras.

       

      So what's the solution to this? I dropped more than $5.5k on a new computer setup for the sole purpose of being able to streamline my photo selection/image management and editing process. Then I pay Adobe $30/mo for this software that is supposed to be the pinnacle of graphic processing and performance, and I get THIS piece of garbage. It's seriously got me wanting to chuck this Mac Pro from my loft window, but honestly I only have this issue with Lr CC. Every other software program that I run on this machine runs swimmingly, and Photoshop manages just fine for the most part - but LR crashes on me CONSTANTLY.

       

      Furthermore, I've gone through all of the "optimizations" that the adobe developers seem to keep referencing. I increased my Camera Raw Cache settings to 15GB (and routinely dump the cache itself), minimized my image previews, turned off my OpenGL settings, and I am STILL getting that beach ball mockingly spinning in my face, maniacally laughing at my seemingly fruitless expenditure on a product that is supposed to be the flagship of creative programs.

       

      Where is your commitment Adobe?! Why is it that your customers can dutifully pay you their hard earned money for a reliable program that, some of us, actually rely on for DAILY BUSINESS SOLUTIONS, and the best you can do is provide a dinky one-page URL with apparently worthless "optimizations" to make LR CC run more smoothly??? I'm sure if we all cancelled our subscriptions, you'd absolutely think of a more efficient and reliable software program to win back our faith - and you'd do so QUICKLY. But because you're the big giant ADOBE - noooooooo.....oh no. You don't need to hold yourselves accountable do you?! It honestly seems like you couldn't give 2kb worth of care to the people who actually CREATE THE FOUNDATION that you now stand upon!!!!

       

      Should I have opted for the $12,000 Mac Pro instead of the dinky $4,000 model? Should I sell my audi and build a 32-core super computer that can somehow make up for this blunted excuse for a tool you wonderful people at Adobe call Lightroom? I just need to know. Please tell me: is that what kind of machinery us users need to purchase to get your software to run smoothly so we can focus on getting our WORK DONE instead of having to quietly avoid panic attacks brought on by the sheer rage that bubbles up from the depths of our SOULS when we put this much valuable time and personal resources into a product which is clearly substandard?!?! Tell me now so that I can look into selling one of my cameras that I need for my life blood just so I can reinvest it into a super-computer, if that's what's needed to get this program to run smoothly work. At least then, you're actually setting proper expectations and people know what they're getting into. Just tell the people "Yes, the program can run on these basic requirements, but if you actually want to get the FULL performance from our product, you need a NASA Super Computer worth of power to make her purr like a kitten. Then----well, MAYBE."

       

      ANSWERS. ANYONE. FOR THE LOVE OF GOD I NEED ANSWERS. Is there a hard copy of Lightroom I can download somewhere? There has to be a way around this. I'm at my wits' end.

          What are the pixel dimensions of your monitor(s)?

           

          What are your photos' pixel dimensions?  Can you post an example photo to Dropbox and include a link in a reply, here?

           

          If you don’t have a 4K or 5K monitor have you turned off Use Graphics Processor in LR / Prefs / Performance, or maybe that’s what you mean by turning off OpenGL?  In any case, do things get faster or slower with Use Graphics Processor turned off?

           

          When LR crashes is it a video driver issue or something within LR indicated in the crash report.

           

          When LR is slow, is the CPU or Memory maxed out for the process in Task Viewer?

            Hi, You're not alone in this, and you're did right that Adobe don't seem to care. I have 6 Macs running this software, and it's a business too like you. It's beyond infuriating knowing something could be done, but isn't.

             

            So Adobe, WHAT ARE YOU GOING TO DO???

             

            There's many of us out here waiting for an answer, while looking into other solutions, I'm switching away from LR very soon if you don't do something..

              Adobe doesn't reply in this forum to questions like that.

                do you mean that he was rude in his question so adobe is going to ignore his thread? I suffer similar issues with slowness on fast expensive machine with 4K monitor.

                 

                Thank you.

                  I meant that Adobe does not reply to questions like that, rude or not. That's not the purpose of this forum. This forum is not a way to talk to Adobe. This forum is primarily a technical support forum from one user to another. Some Adobe staff do provide technical support in this forum too, answering specific technical questions. They do not respond to vague questions of the sort: "So Adobe, WHAT ARE YOU GOING TO DO???" Also, Adobe almost never addresses future plans in this forum (plans that might answer the question "what are you going to do???") .

                      No, I don't have a 4k monitor, which is actually adding to my frustration since this thing is supposed to be able to handle up to SIX 4K monitors at once. I couldn't imagine the kind of lag that I would be experiencing if I were attempting that.

                       

                      No, I am presently running two 29" LG IPS (29UM57) Ultra-wide displays, with thunderbolt adapters. And yes, I turned off the graphics acceleration (unchecked "use graphic processor" box) because before then, the chugging that I experienced was 10x worse. So, you can imagine how much work I was getting done at that point.

                       

                      As far as my memory being over-taxed, aside from the fact that I have a 6-core 3.5GHz i7 processor cranking under the hood of this thing, I also downloaded CleanMyMac 3, which allows me to free up RAM when it is getting overwhelmed. THIS didn't help either.

                        Richie, I passed my point of lividity WEEKS ago - I would have dropped Lr by now if I could find a viable alternative that is also seamless with my other software platforms, e.g. Ps and Ai, which I use often for my publications and such.

                         

                        This seems like such a stupid problem to have! It's almost 2017! There are hover boards and cell phones that can utilize AR API's where people wear the bloody things on THEIR FACES....and yet Adobe can't seem to fix these relatively minuscule issues with Lr. It's just ridiculous.

                         

                        I'm not being rude. I'm just beyond frustrated. Worse, is you can trust and believe, they'll still bill my credit card for the full amount this month! Not 43% of the invoice because I'm only getting about THAT much usage out of Lr...no. noooope. They're still going to charge me/us/everyone full price.

                          How much memory and how much CPU is being taken during the time LR is working on something?  Is memory used up (RAM) and/or is CPU maxed out?

                            I went ahead and posted my gripe to the link you suggested. GOD I hope someone can give me something because my next step is to get someone on the phone. This is unfortunate, because whoever is on the other end will likely not be the programmer, system infrastructure/software engineer that put this thing together. Oh no...noooo no. It's going to be some customer service rep with a kind voice, eagerness to help and some loose understanding of how computers work; but really not a single modicum of useful knowledge on how to actually FIX this.

                             

                            Ya.I anticipate this is going to be the person that Adobe will put at the front line of their defense to bear the full weight of my outrageously inflamed dissatisfaction. Maybe I should listen to some Enya and rub my ears before this happens.

                              CleanMyMac 3 is likely freeing up RAM by swapping to virtual-memory on disk, which will slow things down for existing programs so new programs start up quicker.  So if the CleanMyMac 3 memory freeing function is running while LR is running, LR will likely get slower and slower as more of its memory resides in disk instead of in RAM.  I only have a PC so don't have detailed knowledge of the info shown but if TaskMonitor shows RAM vs VM and a page-faults rate that is useful to know. 

                               

                              There is a bottleneck somewhere on your system.  The questions I'm asking and the sample photo is to help determine if this is something that works on other peoples'; systems and there is just something quirky with yours, or if what you're going isn't feasible on most desktop computers, nowadays.

                               

                              I don't think my PC is that much newer than your Mac and has less cores so I'd like to see how well it performs compared to yours with the same photo.

                                LR phone support is typically limited to downloading, install and licensing support, not troubleshooting.

                                 

                                You'll do better with technical information and answers to technical questions, than ranting and demanding.

                                 

                                Something seems wrong with your computer system.  There is a bottleneck, somewhere.

                                  Here you go. I went ahead and began processing ONE photo....and it's one from my Nikon (roughly a 25MB RAW image file), not my Medium Format camera which has much larger file sizes. I went through my normal Dodge & Burn image process until I got the first spinning wheel of death and the crash recorded on my activity monitor. This crash lasted for 3 minutes AFTER I compiled the screenshots, edited them in Ps, and posted them to this board.

                                   

                                  You'll notice that, while my CPU and RAM is under a heavy load, it's nowhere NEAR being over-tasked.

                                    I'm ranting and demanding, because the squeaky wheel gets the oil. Personally, I'd rather spend my time getting stuff done instead of outside in the rain, shaking my fist angrily at the sky. Bottom line though, is that this isn't a free program, and I've spent way too much money to see that bloody beach ball nearly as often as I do.

                                     

                                    If you can help me find this bottleneck you speak of, I'd be eternally grateful.

                                      "Not Responding" is not a crash, it just means the system is busy doing something on LR's behalf and LR cannot take keyboard input, but obviously something is wrong if that is happening.

                                       

                                      I see this on my PC when my video driver isn't compatible, and when there is too much virtual-memory being used and LR is waiting for the OS to give it back some RAM to work with that is currently swapped out to disk.

                                       

                                      Dodging and Burning is a CPU-intensive function so that may be a contributing factor but I don't think it'd be causing the Not Responding condition.

                                       

                                      Is the disk being used, heavily?

                                       

                                      If you don't do any dodging and burning are things fast?

                                      --

                                      Have you turned off Face Detection?

                                        I use Macbook pro's and don't get the issues you are having there is something astray on your set up somehow. But unfortunately as you just want to rave and not get into details of what happen when and where in repeatable steps..... I guess we won't be able to help. But lets see.....

                                        BTW my system is 2x MBP's - both i7/16GB, one 2011 and one 2014 with internal SSD's for system and apps, external Thunderbolt LaCie for catalogs including one Master of 800k files with previews (total of 604GB) - image files on various thunderbolt and USB drives....

                                        No crashes........

                                        So maybe you can start with saying what is where, why you have minimal previews (they will need to be rendered every image on your screens).. and any other relevant information.

                                        Thanks

                                          From what I can tell, my SSD isn't being overly tasked at all. Furthermore, I have 3 external SSD's running separate from the main internal SSD. While I have all of the apps installed on the internal drive, I have the catalogs being run directly from the whichever SSD the images are being stored on. I actually did this to specifically to avoid over-tasking one drive, thus leaving as much of the system resources to the task at-hand.

                                           

                                          And speaking directly to your question about Dodge & Burn, yes - if I don't do dodge & burn, then the system is relatively smooth. But that brings me to the crux of my primary gripe with this; is that I bought this machine to specifically handle the labor intensive nature of D&B, because my MBpro nor the 27" iMac i5 I had at the time could handle heavy editing, especially on files from the Medium Format.

                                           

                                          Oh and yes, Face Detection is "paused" as I didn't see an option for turning it completely off.

                                           

                                          So how do I mitigate the issue with Virtual Memory being tasked out to something else and starving Lr for what it needs??

                                            Hi Geoff. I'm glad you picked up on the fact that I am angry and was intent on ranting. You know, since I did preface my post with "before I begin my rant....".

                                             

                                            I also don't know what relevance how many photos you have on your computer(s) could possibly have to this conversation, considering I am not ranting about storage issues or anything of the like, it's a performance issue that I only experience when doing intensive editing. Also, I have my image preview resolution cranked down to the lowest settings possible. 

                                             

                                            I do appreciate your substantive input in the matter nonetheless.

                                              Catalog size has been a common complaint in slowing systems ... just saying a large catalog does not necessarily do that.

                                              Tell me where you have Dodge and Burn in Lightroom??? Are they a new tool I have yet to discover??

                                              Small previews will just mean every time you are not using Grid view new ones will need to be made... I recommend you use either Auto or a size up from your screen width ...

                                              Does this happen with only one display in use??

                                              I can tell you that ranting will do little as it masks your points that will help determine the cause...

                                              You can understand the Adobe team run top spec computers and are not seeing this just as most users aren't. Now I'm not saying that there may not be an issue with the software but experience says there is a bigger chance of something astray in your system or methodology.

                                              Oh and which version are you using??? Look under Help>System info>Lightroom version

                                                Dodging and Burning would be use of the Adjustment Brush with lightening or darkening settings set.

                                                  Maybe you can do this on a Mac.  On Windows you can use Task Manager to set a process's CPU Priority (and CPU Affinity).  I remember reading somewhere that starting LR with a Low CPU Priority might help background processing get finished that are blocking the UI thread.   I am not sure if I believe this because setting the process priority should affect all the threads so I am not sure it'd help but you can try.  You can also experiment with High as a priority.

                                                   

                                                  In the olden days, like back when LR was architected, the UI thread would get time to work because there was disk latency giving CPU-bound threads (like the adjustment brush computations) time to work.  Now, with SSDs this latency is gone and things can get in each other's way as well as the I/O bus can get overwhelmed.  You can also set LR's Affinity to a subset or even just one of your processors to see if that helps it.

                                                    And speaking directly to your question about Dodge & Burn, yes - if I don't do dodge & burn, then the system is relatively smooth. But that brings me to the crux of my primary gripe with this; is that I bought this machine to specifically handle the labor intensive nature of D&B, because my MBpro nor the 27" iMac i5 I had at the time could handle heavy editing, especially on files from the Medium Format.

                                                    A lot of brushing (and spot healing) is a known problem in Lightroom, it does indeed cause slowness in the Develop Module, and as you have discovered, in the absence of brushing your system responds fairly well.

                                                     

                                                    There are some things you can do that might speed up the performance of Lightroom in the Develop Module. In no particular order

                                                    • Turn the GPU acceleration off to speed up the brushing
                                                    • Do the brushing (and spot healing) in Photoshop or Photoshop Elements
                                                    • Do the brushing (and spot healing) as the next to last step in your editing, with Lens Corrections and Transforms* off; then as the last step perform the lens corrections and Transforms*
                                                    • Get a faster CPU

                                                     

                                                    * — Transforms refers to the Transform panel in Lightroom 6.6/Lightroom CC 2015.6 and later

                                                      Move to Alienskin Exposure. It has limitations and needs improvements but not that many and you can directly contact them, not thru some 'no care factor' infuriating chat method that never seems to help. I feel so much happier and just wanted to share my bliss after UNINSTALLING LR, PS and Bridge.

                                                        I'm not resurrecting this thread, but I just wanted to stop back in and thank everyone, especially ssprengel for their time and help. Even though I really haven't found much of a solution with this outside of just leveraging Ps to do what typically slows Lr down, it is at least comforting to know that there are others in our community on the consumer level that care enough to step in and lend a thought to help.

                                                         

                                                        So for all of you who participated in this thread, I appreciate your time. Thank you!

                                                          Lightroom is an utterly brilliant program. Lightroom CC however is broken. It's crap and should have never been foisted upon the public. Adobe doesn't care to fix it or doesn't know how. They've made that clear in the past TWO YEARS. The solution is to go back to LR5, which still performs very well. There is literally nothing I can do on an i7 laptop to slow down LR5. Hundreds of spot brushes, gradients, etc. all instantaneous. LRCC chokes on everything, the simplest of operations, regardless of settings. Adobe should issue refunds to all the people who were sold this defective product. Amateur hour at Adobe for one of their most important and beloved products. Adobe shouldn't need a single word more input from users. You are the authors and the experts, fix your product or stop selling it. Geoff completely misses the point. A huge number of users have been making the same complaint for TWO YEARS - the software is ridiculously slow, doing all the same things we've always done in previous versions, using all the same settings. Users here are not ranting enough.

                                                            quindi direi che non è questione di avere un computer o una scheda video potente...è il programma che non funziona!

                                                              Not sure if your concern is answered or not... BUT here's my two cents.

                                                              The steps Adobe provides to help 'optimize' lightroom are good advice and steps that should be taken.

                                                              My BEST experience comes when:

                                                               

                                                              1. Disable all syncing and face detection (file syncing is a HOG on lightroom)
                                                              2. Set all your lens specific settings 1st (Lens Corrections, Camera Calibration, etc) then SYNC settings to all required photos.
                                                              3. Disable all effects in the side panel that do not require color correction. i.e. Effects, Transform, Lens Corrections, Detail, Crop, Spot Removal, Filters and Adjustment Brush.
                                                              4. I always perform basic color correction FIRST, then add the rest back in one by one -- as needed.

                                                               

                                                              With this process my Lightroom FLIES on my mid 2012 MBPR 2.7 i7 w/16 GB RAM and SSD.

                                                               

                                                              LR has to render your preview on the fly and with intensive effects you can understand how much LR has to do on the fly.

                                                               

                                                              Always Sync last.

                                                               

                                                              This is often how my panel looks at step 1.

                                                              After i'm finished with this photo, I enable all settings, let my previews render then move on.

                                                               

                                                              Hope this helps

                                                              PS: I always use 1:1 previews. Anything else kills the speed of my review process.
