Seeing a limit of 20 tasks for my PC's, they have more CPU's (64).
Two months ago, no problem to fill the pipeline with more tasks.
Nothing changed from my side.

My computers seem to have a limit of 80 Theory tasks. They have 8 and 16 CPUs.

20 Tasks is the limit from Theory, but why 485 finished in mcplot?

If you set Max # jobs &/or Max # CPUs to anything other than No limt then it could be there is a cap.

Given how long the tasks take I'm not sure why you need such a buffer of work, I have 0.25 day of work and have 70 on my computer, 36 running and 34 buffer

Only 20 Theory for 64 Cpu's is to low for this Threadripper.
