Which value is better "Worker Management\Minimum Diff" for S7?
The pool will automatically set it optimally for you. Don't worry about it, as I understand it manually tweaking it doesn't do much good in the long run anyway. Trust the code -ck and kano-san are running, best out there!
I agree, let the system automatically set it. If you were to do it manually, you'd need to be constantly revising it anyway.
