Lightroom performance issue
Feb 9, 2019 12:14:03 #
My 'off the top of my head' suggestion is to look into your cache setting and increase it substantially as you have the memory to do so. That has always been a big help for me. From what I can 'gleam' from the web, Adobe does need to, and supposedly is, working on speed issues. As my iMac was getting to be older, I purchased an iMac Pro a few months ago and find it really helped with speed. There is just so much involved here, and you're right, some is buried in minutia! Contacting support may also be a very good idea as I have always found them helpful and useful. Best of luck.

I turned off the LR performance selection telling it to use a graphics card and have used LR for a little while. It may have helped, not sure yet, I need to use it for a longer time period. I will give you an update. Very surprising to me. I don't know why "unchecking" using the GPU should help.I have a low end graphics card and perhaps LR is trying to use more resources than it has & the LR code is not "smart enough" to know that.....If you do not tell it to use a graphics card, it does not do that? I also turned on some GPU monitors, (did not think it necessary before), so I will keep observing & see what happens. thanks,

I extend my sympathies - I used to have the same issues. They cleared up when Adobe introduced some performance enhancements to LR. Unfortunately, I'm running the exact version and build number as you are. Where I noticed it was when I was doing extensive keywording. Just a thought - have you tried turning off the graphics processor to see if that changes anything?

Yes, A good suggestion. I am monitoring temps ( usingHWiNFO64 & Sysinternals apps). I have Lots of cooling , so I am no where near having heat issues.

Have you considered using an application to monitor CPU and disk temperatures and CPU frequency as performance slows? See the CPU performance vs temperature charts in this article as an example of decrease in performance with rising temperature: https://www.pugetsystems.com/labs/articles/Impact-of-Temperature-on-Intel-CPU-Performance-606/

No app seems to be using up resources. As I mentioned, I am at around 40%-50% for both CPU & memory usage. When I am not doing any edits in LR, CPU is low around 15%...

Crank up the task manager and try to see how many apps are running and who is chomping up all the resources. See what apps are coming up at boot time and see if they are really necessary. Did you install and new apps about the time it started slowing down?

As I mentioned, I am at 50% memory usage when this happens, so more memory will not change the problem. As to using a high end video card, I was going to try that, but I thought ( this info might be wrong or for an older version) that LR does not really use much of the resources of high end Video cards. But, from what you say, perhaps I should get a better card. thanks,

Lightroom really needs more ram, not less than 32mg works for stills but 64 mg for video, additionally my issues went away with high end NIVIDIA video cards designed for gaming.

Lightroom appears to have gotten slower and slower over the past year as Adobe has been adding and/or modifying the software, even on a fast computer!

How about disk?

I listened to the video. He has some good tips. Some I didn't know. One comment of particular interest to me is his mention of issues if you select the performance option to "use graphics processor". Seems like LR sometimes has issues with this selection. Might be my problem ( as I mentioned in a response about an hour ago). This issue is recent for me, so if this is the cause, it is a bug in one of the recent updates. I have had that field checked for quite some time. I would think about upgrading to a high end video card, but I don't have confidence Adobe programmers know how to properly code for one and I could just be wasting money. . Does anyone have success with choosing a compatible card? Thanks.

Not sure what your question is. I have LR and photos on 2 SSDs
You checked CPU and memory usage, but performance monitor will also allow you to see disk usage % which will tell you if you’re I/O bound or excessively paging to disk/scratch space, which will kill performance. You’re running with SSDs, which are fast, but nowhere near the speed of DRAM or L1/L2 cache. Just examining all the HW usual suspects before settling on SW/app as the problem.

I can tell you that the card in my iMac Pro (base model) works very well with Lr Classic CC. Even supports two monitors. Best of luck.

Your configuration is nearly identical to mine same versions of software. My C: drive SSD is 500GB. I put catalog on the SSD with the recent originals. And I have 16GB installed. But none of that would explain my lack of slowdown. My processor is an i&-3770 @ 3.40GHz, cannot be overclocked. I thought that might be overheating except you checked that and it wouldn't recover quickly by restart. I have a different video processor originally on Adobe OK list where it crashed, then a older version of driver recommended,and now OK except I became convinced it was faster w/o it and turned it off. But actually I have no clue! If you do solve the mystery tell us so we can be on the alert. BTW I find later versions of LR to be noticeably faster with the performance improvements that began last fall.

Interesting. Im running on a MBP with 16GB ram, I don't have the problem so it is no systemic.
Your problem is repeatable so there is hope of solving it. You try might firing up Acivity monitor and watch it over the course of 30 minutes, see if there are any changes. Look at CPU and memory, pay attention to swap used. Might be worth a trip to the local Apple store, talk with a Genius, show him the problem. Or you could try Adobe support.
