The id outliner operators take 2+ minutes each to complete. CPU usage is at 20% and RAM is at 50%.

Specs:

CPU

Intel(R) Core(TM) i7-10700K CPU @ 3.80GHz

8 Cores

Memory 32 gigabytes

I’m no hardware expert at all, I copied this from my task manager screen.

These are heavy blend files full of library overrides, but the slowness would be justified if they had filled my cpu and memory, which they don’t. Is there a way to optimize this? I’m getting more and more nervous and frustrated.
