P: Slow performance on Xeon CPUs

I specifically use a 4k screen for editing but also for coding since all the text is easier on the eyes for longer durations of times.

But seriously -- even if not photography 4k isn't really exotic anymore. It's mostly gamers that still buy 1080p screens.

What i would like to see is that the Develop Module in Lightroom is 100% dedicated to the task at hand. Editing photos shouldn't be anywhere near slow on a modern system.

Hi All,

I have a Laptop specifically for high end graphical 3d modeling so photoshop and lightroom should be a breeze, Actually photoshop is, However like all of you, Lightroom is dog slow..
I can make a temp tonal adjustment and 7 seconds later the slider might actually move and I might actually get to see the change, this is unusable when you have hundreds of images to go through,

My setup is a Quad core Xeon E3-1535M @ 2.90Ghz hyperthreaded giving 8 threads in total.
64GB Memory, 4K screen, m.2 samsung 950 Pro Getting 2,000mb second read and writes,
Graphis is using the Nvidia Quadro M2000M  with 4GB memory

Having moved from my desktop Imac I5 3.2Ghz I have shattered to see that my power laptop is so much slower.
I have read all the threads here and so resulted at looking at alternatives, In doing so I found a way of speeding up lightroom on my system, Not lighting fast but so much more usable without much lag.

I installed the demo version of On1 photo Raw 
in developer mode of On1 it is even worse than lightroom.
However what I noticed was that, If I leave On1 running in the background and then launch lightroom, Lightroom seems now to be so much faster, If I close On1 down and launch lightroom then Lightroom seems slower again.
On1 during installation will install plugins to lightroom (not sure if this has any affect)

My next task will be to look at my graphics drivers and to also test capture one pro.
I shall be following this thread for potential fixes.

I have also tried disabling hyper threading which made no difference.
I also fired up a Win7 VM using 1 processor but again this made no difference in performance.
I shall welcome any other fixes to try and hope Adobe get on top of this.

I think you are correct, 368.39 seems to be marginally better than 375.95 [typo above!]. Speed of LR tools is still slow however.

Well, well! Nvidia not up to date and I have updated to 735.95 which has improved general display performance.
I still can only get a few minutes of action with the localised adjustment tools before the program comes to an effective standstill. Whilst using the Graduation Filter I can swing the Temp Adj slider from one end to the other without getting any response within an acceptable time, at least half a minute!.
I guess I will have to get up to speed using PS adjustment layers or pray that Adobe gets its act together quickly.

My Nvidia sytem tells me the driver is up to date! Time to investigate further, thanks.

Have you tried updating your graphics driver? There were lots of problems with drivers between 369.x-374.x and are not supported.

I generally never upgrade any driver unless there's a specific issue.......I made an exception this time and it came back  to bite me. I won't be doing that again!
