I mentioned that I was not surprised the LR Team "hit a wall" with LR4 and that was a testament to how far they have "pushed the envelope." Whether you agree that's the case or not pretty it's clear many people are having "unexplained" performance issues with LR4, some with very high-end systems. We have identified one issue when using high resolution monitors greater than 1920 x 1080 and dual displays. I don't see any way for Adobe to correct this with the current system processor technology unless they add Open GL/CL support for offloading screen image building to the graphics card GPU cores. Open GL support for display acceleration was added in PS CS4 almost four years ago. I'm not an internals programmer and don't know what would be required to add Open GL support to LR. My guess is it will only happen if/when Adobe decides to do a major rewrite of LR, since we know there are other issues that adding Open GL will not fully correct. ... View more

The 1 Megabyte main memory required 16 boards measuring 15" x 15" installed in a 6' foot tall 19" rack, using ~5,000 DRAM chips. A 1 Megabyte memory expansion cost  $10,000 in 1978 dollars. Today 4GB of memory costs less than $30. In 1978 the cost of 4GB memory (if even possible) would have been 4GB/1MB x $10,000 = $40,000,000 and that's using 1978 dollars! Today's computer systems, OS, and applications are several orders of magnitude more complex than what was used for the Apollo 11 launch.  I was there first-hand, worked with the technology available, and still working with computer technology today.

SavagePhoto, I feel your pain! What model, processor, memory and any other options. Also, how did you move over the previous LR installation, or was this a totally "fresh" catalog? To eliminate merely "moving over" a problem from your previous system, I would suggest trying a test install using a new catalog, cleared preview folder, and purged camera raw cache. Then re-import a small number of raw image files (no DNGs, or XMPs) and see how it performs. If this is exactly what you have done, then there is another issue. If not, try a fully "clean" install to test it? It should only take a few minutes. If that works we can try to find out what's wrong with your original catalog, etc. and get it onto the new laptop. Either way, providing the specs for your new laptop will help people here like bakubo who need to upgrade their system. ... View more

So we can get a better idea on your LR responsiveness let's try a more analytical test. In Windows 7 open the Resource Monitor by hitting CTRL + ALT + DEL keys, click on 'Start Task Manager,' and then click on 'Resource Monitor' at the bottom, and then click on the 'Overview' tab inside the Resource Monitor. Next open Lightroom in the Library module to a folder that has at least five (5) raw image files. Click on the first image and wait for it to fully render onscreen, then click on the next image and wait for rendering, and repeat. Immediately select the Develop module and repeat the same procedure, waiting until the 'Loading' popup goes away for each image. Next very quickly toggle to the Resource Monitor, click on it, and hit ALT + PRT SCR keys. Finally paste this screen capture into any editing application, save it as a JPEG, and insert it here in a reply post (i.e. the camera icon). If your system is slow use only as many images that will fit into the Resource Monitor window (i.e. 60 sec.). I was able to use five (5) images, with the Library module taking less than .5 sec. and Develop module about 4 sec. for each image. It should look like the screenshot below. ... View more

Using LR in dual display mode is not an issue in of itself. What is ithe issue is the size of the Loupe window. As you increase the Loupe image resolution the more processor intensive Loupe image rendering becomes in the Develop module. You can verify this by hooking your external display back up to your laptop, but resize the Loupe window so it only fills about 1/2 the screen.

My system (see August 29, 2012 post) has about 1/2 the performance of yours and I don't have any speed issues. Obviously there is something different with your system that is causing the sluggishness. I'll repeat this again: Preview building and exporting in LR work in the background. This allows you to continue working in LR, provided you have sufficient system performance. How much performance required is dependent primarily on two factors: 1) Raw Image size (Mp) 2) Display(s) Resolution (dpi) and use of Dual Displays. If you can provide the above information it may shed some light as to the root cause of your LR4 performance issues. Concerning slow LR Exports, I believe Adobe has purposefully limited the processor utilization so you can continue to work in LR. This is at least the case for systems with processor that support hyper-threading, like your i7-2600K and my i7-860 processor. You can "force" LR to Export with higher processor utilization by breaking up your export into two or three groups running simultaneously. On my system running three Exports pushed processor utilization to almost constant 90-100%, which made working in the LR Develop module very sluggish. During normal Exports there is only a slight decrease in LR's "responsiveness" when using Canon 5D MKII 21.1 Mp raw files and a single 1920 x 1080 display. ... View more

Cinobite I told you I have an i7-860 (2.8GHz) processor that has barely 2x the performance of your Q6600 (2.4GHz) processor, and I'm not experience the issues you describe. I'm also able to work inside LR while importing images with preview building, and during exports. Clearly some people have LR4 performance issues and for many different reasons, including people with very high end systems. There is no one solution that "fixes" all LR performance issues. Preview building and exporting in LR work in the background. This allows you to continue working in LR, provided you have sufficient system performance. How much performance required is dependent primarily on two factors: 1) Raw Image size (Mp) 2) Display Resolution (dpi) and use of Dual Displays. If you can provide the requested image file type and display(s) it will give more insight as to the root cause of what you are experiencing, and possible solutions. The Intel Q6600 processor in your system was introduced in Q1’ 2007 over five years ago and doesn’t support hyper-threading: http://ark.intel.com/compare/41316,29765 Lightroom does support hyper-threading, which can be seen in the below Windows Task Manager screenshot while “browsing” multiple images in the LR4.1 Develop module. LR Exports and 1:1 preview builds have even higher processor utilization, but I’m still able to work in the Develop module with no sluggishness. To verify how much hyper-threading helps LR4 I ran benchmarks with hyper-threading enabled and disabled. Interestingly the benchmarks were almost identical, but LR lost its responsiveness in both the Develop and Library modules when 1:1 previews were being built or images were being exported. With hyper-threading enabled all eight threads never reached 100% utilization (see above screenshot). With hyper-threading disabled utilization rose to near 100% for all four cores during 1:1 preview building and during exports. This may be one (1) of the reasons why LR becomes sluggish on systems without hyper-threading. ... View more

Cinobite wrote: Installed RC 4.2 ...... now it's even worse. I'm sure someone asked me if it takes the same time to export as it does to render the preview. Yes, I think. Clicking a photo takes 10-20 seconds to render 1:1, exporting takes about 14 seconds per image. I'm fine with the idea of creating 1:1 previews on import, but all this is doing is putting all of that time at the start of the session so overall makes no difference only takes up more space. In fact it's worse, if I have 1,000 photos to import and use 1:1 previews that's nearly 3 hours to import. I might then cull 400 of them. I'm even happy to spend £1,000 on upgrades and build a stupidly high spec machine. But in all honesty, I don't think it will make a difference. I ran LR3 on 4GB RAM. Then by about 3.3 is started slowing down so I doubled the RAM to 8GB. And it didn't make a difference. Really isn't acceptable. I never had this issue with LR in the past. I'm running on Win 7 64 bit with an i7-860 quad core processor, 12 GB RAM, and standard 1TB 7,200 rpm HDD. My system has ~2x the performance of yours, so I would say your posted times for 1:1 preview and exports are as expected. On import of my 21.1 Mp Canon 5D MKII raw files with 1:1 preview rendering I am able to start working on the images almost immediately with the preview images rendering in the background. My 1:1 preview build time is about 11 sec., but like I said it doesn't stop me from working in LR during the import process. The long delay time when switching between images is not something I'm seeing. Once 1:1 previews are built I can switch between images in the Library module and zoom to 1:1 with no delay. In the develop module it takes about 4 sec. to render when switching between images, which is why you I do all image review in the Library module. Please check out this post for possible cause of the long render times you are seeing when switching between images: http://forums.adobe.com/message/4597477#4597477 What display resolution are you using and are you running dual display mode with LR (primary and secondary)? ...
