    Lightroom 4 (and update) slow down after editing 2 images

    greatpix-55 Community Member

      Imported 74 Nikon RAW images (from D300) into Lightroom 4 (also tried with RC-1) on 2.8ghz Intel iMac with 4gb memory, approx 180GB free on 320GB HD.

       

      After using the brush on 2nd image the program slows to a crawl. It takes a minute or more to load the next image, a dozen or more seconds for Brush to be ready to use. Running OS-X Lion. Getting spinning wheel constantly, and it gets slower after 2nd image. I'm forced to close the program, wait a bit and restart so I can edit another photo in any reasonable time. Also, if I wait in Lightoom, doing nothing for a minute or more, things will speed up again for another 1 or 2 images (if I'm lucky).  All software and OS is up to date. No other programs running.

       

      Memory leak or garbage collection problems?

       

      Same thing happens on my Windows 7 laptop using a new Crucial 120gb SSD.

       

      Someone else is editing the same images on their 4 year old PC using Lightroom 3.6 and everything is fine. I'm switching back to see if it helps. Will post here with results.

          Went back to using Lightroom 3.6. No slowdown, MUCH faster.

           

          Tried the LR 4 RC1 and no improvement. Sticking with 3.6 until LR 4 is ready for primetime. Adobe should have left it in Beta longer.

            Yep same here. Using the RC, rendering 1:1 and all the other optimisations reccomended. The program is not as responsive as LR3.6 but as SOON as I touch Noise Reeduction or Spot Removal then the entire program grinds to a halt while it takes five minutes to make the last adjustment. That's the end of the editing session for me. It's unusable and a complete waste of money and it is clearly affecting a lot of people. Back to 3.6 and I think time to ask Adobe for a refund (and yes I can hear you laughing in the back sir).

              I can confirm the issue. Using some function (I noticed it on noise reduction too) causes a tremendous slowdown.

               

              I'm using a i72630QM with 8gb ram. It's fast enough to handle that stuff, at least it was on LR3.

               

              Edit: just to clarify what I mean with "slowdown": the program is barely reacting anymore, takes several seconds to come back from minimize, pretty much feels like crashing nonstop.

              I can say 99,99% certainty that its not hardware related.
