P: Slow performance on Xeon CPUs

I noticed that LR clone and brush tool on my XEON E5-1650 0 3.20GHz (Attention: E5-1650 0 and not E5-1650 v4) can not stress my CPU and after x minutes of working LR slow down, until I have to restart it.

Please see the full diskussion with the problem here: https://forums.adobe.com/thread/2210245 (test with different Lightroom versions, confrontation with a weak laptop, that works fine, tests wit other graphic grafic card, test with other bios settings etc. No results. Only restart LR or minor display resolution helps.)

Can anyone with an XEON E5-1650 0 3.2Ghz confirm this?

    Smart Previews are very cool.
    But... After doing the Exports LR sticks in being slow. Damn.

    What i need: A Converter that converts all LR-Presets to Capture One-Presets.
    Seriously, i will give it a third try whenever i got some spare time.

    I've noticed something similar. When first starting the import of photos, my rig will convert an image to DNG in about 4 seconds. After about 20 minutes that number grows to 15 seconds. The longer the computer converts images the longer the convert time is. I've recently seen my take up to 30 seconds to convert a single image. Again, this is not right and should be treated seriously by Adobe.

    Hi Simon, If you are still reading this thread, here are some timings about the slowdown in exporting/importing 24MP nefs onto an internal HDD. Using Haswell-E cpu i75930K with all 6/12 cores.

    Average cpu usage (Resource Monitor, Win10)

    Initial      84%, all 12 usage graphs similar in appearance, hitting 100% much of the time.

    After 5 minutes    74%

    After 10 minutes  69%

    After 30 minutes  50%

    After 60 minutes  41%

    ........................................................

    At that point I stopped the process and waited until all cpu and disk activity had died down, and then I restarted the export/import process.

    Initial     41%, ie simply stopping the process and resuming it had no effect, it was still slow.

    ..........................................................

    Then I closed LR, restarted it, and resumed the export/import process

    Initial    88%.  So closing and restarting LR (CC 2015.9) put the process back at full speed!


    Any help?

    Hmmm. I'll run some tests and report back. Thanks,

    The difference between smart previews and 1:1 previews with my images is enormous. My D810 nefs are 36 MP, so 1:1 previews will be the same size. But Smart previews are only 4.3 MP (2650x1706) so the difference in size is a factor of 8! So rendering 4.3MP might only take 1/8th of the time that a 1:1 takes, ie your 48 hours with 1:1s might only be just 6 hours with smart pixels.

    Just curious, is there anyone exibiting this same Lr slowness when using an AMD/ATI graphics card by chance?  Trying to determine if this is just affecting users with Nvidia graphics cards

    I only use 1:1 previews and editing is glacially slow. So, I don't see evidence that it's a problem with Smart and 1:1 previews.

    You're right, this is not professional. I've have exactly the same specs as you and it took my rig 2 days to import 4,350 photos. All I did was convert to DNG and build 1:1 previews. This is insanity.
