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?

    The fear of Adobe to acknowledge to their community that lightroom performance is below standard for a very long time has resulted in a lot of anger hate and suffering to say the least. Use the Force Adobe, Rewrite Lightroom and get us all off the path to the dark side.

    It saems noticably amount of users stopped using it. Capture One can afford to raise the prices. Or it is just time buying (again).

    Looks like Adobe has finally decided to listen to it's customers. Please take the time and fill out this official survey: http://www.canonrumors.com/do-you-wish-lightroom-was-quicker-adobe-does-too/

    I am losing the will to live......adobe needs to get their finger out, my i7 can happily churn using all cores on Lightroom processing, it needs them but when I am working through adding keywords I gradually get slower and slower performance until I get a non responding lightroom. If I kill lightroom before it becomes terminal my PC continues with no issues. Basic software problems on professional, and not cheap, software really isn't acceptable in this day and age.

    So why aren't you using Smart Preview edit mode with 80MP phase one files? The whole point is to give you a proxy file to edit. Similarly, you can batch convert your 80MP files into 20MP proxy DNG and swap them out after you edit.

    OK FOLKS: 
    I made extensive testing, to answer my curiosity why some guys have no problem and some have and why my 5 year old laptop performs better than 6-core monster workstation. Here are my conclusion: 

    Adobe sucks... ok, joke aside. 

    Lr normal uses up to 35% of my CPU and cpu cooler does not even wake. For regular slider tweaking it is semi-smooth. For using more intensive slider like barrel and  NR, it starts to "build up" and I nned to leave it to settle. My other processor always pump 100% out of CPU, so it does never "build up" in  the queu line of commands. Lightroom does need to "digest" if I slide to much and go back and forth with images too quickly. So for culing Lr sucks as it is. 

    Using perspective correction sliders it stals. CPU is 15% max and just one CPU is peaking at 80-90% while load balancing does jump that single proces to various cores. CPU cooler goes like mad since ONE core doing something. Of course overal CPU temperature is not even warm, but that proofs just one core is doing something. The tool is useless! Almost the same is with local brushes. CPU is going from 10-20% and only evry second thread is used (6 out of my 12). CPU coller spins fast, brushes are jittering and are not easy to work with. 

    BUT Lr pulls 100% CPU while importing images, rendering 1:1 previews and EXPORTING. It really blows through 100's of images on my monster machine. :))

    NOW famous "config.lua" :))))

    Editing is now smooth like butter. YOu can not overload CPU/buffer no matter how quickly and long term you slide like madman everything from A-Z. Even perspective and NR... Now we are talking editing! CPU jumps up to 85%... CPU cooler spins slightly more than nothing. Lr seem to work normal now. But...

    There is no real difference in local brush performance. The perspective correction is much improved now and is usable again. 

    But not so fast. The "config.lua" have it's price! Sicne we are effectively disconnect half of virtual cores that reflects on importing, rendering and exporting performance, which now tops at 60%. 

    And the nVidia GPU problem is there. If enabled, the brush effect/overlay is not visible until you stop brushing. If disabled, the brush effect/overlay can be seen, but movement is not smoot either. It can just jump somewhere... or stick to the mouse when button is already released... 

    I will not use the hack, sicne it is not solution, and I mostly use Lr just for DAM. There is other processor that have no probles at all. They just significantly raise the subscription recently which speaks for itself. 

    And the answer Why low end systems does not suffer:

    The problem as it seems effects only i7 processors. More cores greater the problem. While i3 processors have HyperThreading, it is unlikely that many does use it, and if they, they do not expect super performance out of it, or are probably some begginers that does not hit the roof of Lr capabilities so easily. But most users does have some sort of i5 processors which do not have HyperThreading and so their system does not have such a problem when Lr want to squeeze more threads than it should at the same time, which obviously clogs the pipeline of high end machines with great number of cores and HT.

    Hi Simon,
    for me the main issue is the degradation in performance after working on images, this affects the in develop module, creating panoramas, doing spot removal and file export. So I have to restart every 5 minutes and to be honest many times I just carry on working slow. This is painful on 80MP phase one raw files. however after restart things are much faster for few minutes which shows you can have it fast already.

    when lightroom  become slower (after 5 minutes or so) the CPU usage do not reach as high as it would after restart. It as if it has a cap of how fast the software allows it to use the CPU resources.

    if there is a switch we can try which will force the allocation 100% priority to the current task (e.g. working in development module or doing export) let me know and I will test it.

    it is very frustrating as I have reported the performance degradation in lightroom 8 mouth ago

    on the positive side, at least you are talking to us now.

    Lr 6.10.1 is a minor release for additional camera and lens support and some critical bug fixes introduced in the last release. The team is still investigating the issue and the config.lua workaround would continue to work in Lr 6.10.1. Depending on the customer feedbacks and internal validation, we might make the config.lua workaround a permanent fix in the coming release.

    How does people feel about the current config.lua workaround so far? Thumbs up, thumbs down, makes no difference? It may not solve all the performance problems that people reported in this thread. There are other leads that the team is following up.
