Thumbnail loading performance

[winterNebs]

Hi everyone,

I have a lot of images in the .lepton format (compressed jpg that requires some cpu to decompress), and was noticing pretty poor performance loading large folders with a lot of lepton images.

I was wondering if there was a way to increase performance, I have an i9-10850k and see that CPU usage is barely 20%, and the app will freeze occasionally while loading thumbnails. Is there a way to utilize more CPU via multithreading?

Any suggestions would be appreciated!
