        Unfortunately, Color noise reduction slider has always been at the default, which appears to be 25, on my systems.  If this is "significantly faster" I shudder to think what it must be like when it's NOT in this "significantly faster" setting. 

         

        As time goes on, and I actually try to WORK on things on LR4.1, the appalling slowness becomes more and more apparent in many areas.  Yes, working in develop is just plain SLOW, no matter how many images you load or how many times you load them.  The library module is MARGINALLY faster, but it's sure no speed demon.  Cetainly significantly slower than V3...

         

        And, it appears that ANOTHER month has gone by, and STILL no information from Adobe that they're AWARE there's a problem, WHAT they're doing, and/or WHEN we're likely to see a version that makes significant improvements.  800 pound gorilla syndrome?

          I have just been using LR4.1 and happened to be printingfrom my Firefox browser as well. It locked up LR for several seconds. I mention this as it might be a clue as to what is going on. Memory leak maybe, with the printer driver over-writing some memory address LR was trying to use? The developers need all the info they can get I'd guess.

            After weeks of absolutely nasty performance with LR4.1 I today tried the trick someone posted here a while ago. I started LR via a batch file:

             

            start "lightroom" /high /affinity 15 "c:\Program Files\Adobe\Adobe Photoshop Lightroom 4.1\lightroom.exe"

             

            And to my surprise it WAAAAAAAY faster! I know that developing multithreaded apps is quite demanding but what Adobe's dev delivered until now is just CRAP!

             

            My machine: i7-3930 hexacore, up-to-date chipset X79 and two fast SSDs and 16 GB RAM - more than fast enough you would think...

              Did you try setting affinity and priority for the LR application through the Task Manager first? I am just curious about that verses via a batch file?

                It is the same resutls just the bat is easier since its a one click launch.

                    You go tmy attention.  LR has been giving me fits!  I am reloading it daily and Adobe support has no clue what they are doing.  I was thinking I needed to completely remove LR and start over but would like to give this solution a try.

                     

                    Could you explain how to create a batch from your code.

                     

                    I tried pasting it into the apple script editor but it wont run.

                     

                    Thanks for the adivce!

                        Sacha_'s script is Windows-only.

                         

                        Note: I start Lightroom at below-normal priority, so multiple simultaneous exports don't influence video watching etc, and it does not affect Lr performance.

                         

                        I recommend checking whether it's the priority or the affinity that is helping the most.

                         

                        If it's the former, then perhaps some other app or service is competing for CPU, if it's the latter, then you've been bit by a bug  that's keeping Lr from using all cores as it should - dunno what the origin of such a bug would be...

                            When I was developing/troubleshooting this bat I found that the affinity was most important. On my system I have 4 acutal cores and 4 hyperthread. If I use ANY hyperthread performance dies. If I use all 4 main cores performance slows. By setting it to use only 3 main core and then setting the priority to high windows does a nice job of leaving LR alone and running most everything else on the remaining main and Hyper cores. My results were undenyable that LR has issues with hyperthreading at least on my intel chip and asus motherboard.

                              Up to 74 pages on just this thread, and no real solutions from Adobe.  My biggest issue is the lag switching between modules after first starting LR4.1.  Specifically, it takes upwards of 25 seconds for the Book module to load the first time (this, on a 2010 MBP with a 7500 rpm drive and 8gigs of RAM). 

                               

                              When Mountain Lion comes out next week, LR4.1 will most likely be replace by Aperture.

                                I hope you have forwarded this information to the Lightroom team.  I'm on a MacBook Pro and haven't yet found the tools to disable specific cores or hyper-threading.

                                  Only think that KILLS me is that there is only one tool keeping me in LR over Capture One and that is the brush masking.... There are many other ways to do use this but I use this A LOT and no other process seems as seamless. Unfortunatly on PC there isnt another Raw app that does this as well. However the final results are better with the free Raw Therapy and Capture One.

                                    I hear ya. My ASUS+AMD board has no such problems (M4A89GTD): all cores shoot through the roof when doing something that warrants multiple cores. - mostly speedy too (some things are slow due to Lr s/w design...).

                                     

                                    I've never heard of any other problems with AMD chips, but maybe that's because so few people seem to be running them.

                                      I rarely use the brush masking. The one thing that keeps me using Lr over C1 is the quality of results (ok 2 things: I depend heavily on Lr plugins).

                                            The disk is fine.  It's a 500gig 7400rpm HD with about 20% of the space used.  2010 MBP with Intel i5 2.3GHz, 8gigs of RAM.  There's no real reason for the length of time it takes for the modules to load.  And yes, I've even tried doing a clean install of Lion.

                                              I responded in his other thread. It is disk load time to bring the templates into memory from disk.

                                                I know you're miffed. But, seriously: why 25 seconds to load the Book module - that sounds abnormal to me.

                                                 

                                                I mean, if Lr were performing abnormally for me, I'd be miffed too. - it's one thing to be disappointed with a normally functioning Lr, and another entirely if your perception of Lr is being influenced by abnormal performance issues.

                                                 

                                                Believe me, I have my gripes too, but Lr is mostly fast in develop mode, once loaded, and mostly fast in library mode, once previews are available. So I am mostly happy with Lr performance. I have my complaints, but it's *far* from "unusable" or "molasses in winter"...

                                                    Book module took about 8 seconds to load (the very first time ever). But now after Lr restart it comes up in about 1 second, first time (subsequent times are instantaneous).

                                                      Just measuring bit-throughput, it is slow. But how many templates have to be loaded (many files take longer than one file) and what has to be done with them?  It is 300 mb of data read from disk in descrete chunks.

                                                       

                                                      In the other thread I reported 8 seconds for the first load of Book. 

                                                      After killing Lightroom and letting memory relax, Book takes 2 seconds to load on a subsequent load of LR

                                                      in the same session going to develop and back to book takes less than a second.

                                                       

                                                      8 Seconds VS 25  on similar RPM disks (yet different data buses) is a breeze. I would be cheesed at 25 seconds but I don't notice 8.

                                                        First time with Book on an old (2.5 Ghz Core 2 Duo) MBP took over 25 secs to load, but subsequent loads are 2-3 secs. Now I have run Book on this catalog before-it lives on a FW800 external, but not this machine. 25 secs everytime would be painful.

                                                          I have a 2009  2.4 GHZ Core Duo MB (the month before they turned my model into a MBP) with 4 GB of RAM catalog on local drive. Load time for book is 15 seconds initially. 2 seconds subsequently.

                                                              Going back to Rikk's reply of 8 seconds to load Book...

                                                               

                                                              I never use the book module, so I"ve not tried to load it previously.  But, just for fun I just fired it up from Develop......  And started counting seconds on the wall clock...  I kid you not, and I'm not exaggerating........  It took almost 40 SECONDS for the thing to load and display...  So, whatever's going on with the 25 seconds, I"m seeing it too.  Once it loaded, I could go back and forth between Book and Develop in a second, but the initial load was incredibly slow.

                                                               

                                                              And I'm not using the batch file to start things...  During that 40 seconds I watched CPU 0,2, and 4, and they were very busy, although aggregate Usage was in the 25% range (which I presume wants to check all 8 threads, of which I"m only using 3)...

                                                               

                                                              Does the book module take a long time for the initial load for other PC users?

Significant, to be sure, but not extreme. And, I consider this "normal" performance.

Anyway, I think it's worth keeping in mind whether we're talking about normal slowness vs. abnormal slowness.

Personally, I'd like to see some optimization, but my point is that it's normal...

But if it's too much slower - you got a bugaboo problem.

                                                                            Anyway, if Lr4 is over twice as slow as Lr3, then you have abnormal Lr4 performance. However, the times I quoted for D300 raws (2-4 seconds), which you say are over double what you saw in Lr3, are not anywhere near double for me. Are you saying that you were able to render D300 raws in less than 1-2 seconds in Lr3? - not me, maybe I had abnormal Lr3 performance and didn't even know it...

I started LR via a batch file:

                                                                                 

                                                                                start "lightroom" /high /affinity 15 "c:\Program Files\Adobe\Adobe Photoshop Lightroom 4.1\lightroom.exe"

                                                                                 

                                                                                 

                                                                                This actually slowed my LR4 down by half on an i7 with 16Gigs.
