Lightroom getting slower and slower

Hi everyone, 

I'm using Lightroom Classic and for some reason it is just getting slower and slower.

 

- All of my HD's have plenty of free space.

- I start a new Lightroom catalog every 2 weeks so each catalog won't have more than 1-2000 images in each. 

- I've increased the Camera Raw cache to 24GB

- Graphics processor is on auto (i've tried turning on and turning off)

- I've reinstalled LR CC twice now and it's still the same.

- No antivirus or firewall etc

 

But Lightroom is still just getting slower and slower to where I now have 10 seconds of spinning beach ball after every click. Soon I won't be able to use it. 

 

I often have activity monitor open when working, and it never used to get into the yellow, but now it is. As soon as I quit Lightroom my whole computer speeds up instantly and the memory usage drops drastically. 

 

Is there anything else I can do?

Many thanks
Steve

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Thank you! I'll give that a go updating and then can always roll back.

 

Yeah before I updated to LrC 10.1 everything was fine. I can't believe an update killed my machine so badly.

Thank you for the heads up on v10.2 

That seems to have solved the problem!

 

This problem only seemed to happen once I had updated to 10.1
