Lightroom Classic CC: Slow switching between photos

Good god.

Why is LR, after 11 years, still so flippin' slow at switching between photos. Library Module, Develop Module, every hardware, RAW type and software configuration known - it makes no difference. LR crawls through photos and it's getting to be a bit ridiculous. I'm not asking for much - just faster than 3 seconds moving between 24MP RAW (CR2 and RAF) files on a 4K monitor. I don't care how many features Adobe adds at this point.

I just want speed -  speed like every other software seems to be capable of providing, but for whatever reason, alludes LR. 

I'm sorry for venting, but I edit about 500 photos per day and those 3 seconds between photos really starts to add up.

jbedford, could I get some system specs from you?

OS?
Version?
Processor?
Video Card?
Ram? 
Hard Drive Configuration? 

3 Seconds is a long time to wait when walking images. Is Library or Develop slower?

Enabled. I've tried disabled but it makes little difference. Having GPU enabled is faster though, marginally. 

It's not always 3 seconds, but most times it is. Sometimes it's one second. Sometimes it's 4 or 5 seconds.

I will be at my Windows 10 system tomorrow (with a 3.5k Monitor) and will try to replicate. I only have GTX 970 available but it should be a reasonable comparison.  I will let you know how I fare.

Update:

I ran some tests on my Win 10 system as promised and, with GPU enabled, was not able to see the same types of image walking times.  Either in Loupe or Develop, with the film strip active, I was seeing consistent times well under a second. 

One thing I've done on my system was to follow the instructions here for configuring the nVidia drivers. https://www.winhelp.info/boost-lightroom-performance-on-systems-with-nvidia-graphics-chip.html

Might be worth a shot?

Hi Rikk,

I've already enabled the high performance mode on the graphics card, so I don't think that's it. 

Subsequently I tried re-overclocking my system to which I achieved a (mostly) stable 4.38GHZ (from a 4.2GHZ max OC) from the processor and a ram overclock too (1333 ----> 1903). I've noticed speed improvements in LR right away which makes me believe that the slowdowns are coming from a caching issue between the CPU and RAM. Could I be on to something? I'm no engineer, but maybe the ram is playing a more important role in LR performance than I originally thought.

Thoughts?

Interesting notion but I am the wrong guy to ask here... I tend to drive the speed limit on the highways and my processor clock speeds.
