There seem to be still small issues, but I wasn't able to pinpoint them to a scenario (I'm not even 100% sure they are related to the CPU scheduler, could be IO elevator or VM too). Just thought I would mention them. Occassionally (very seldom, saw it two times yesterday) I have visible stalls (2-3s) of my xterms. It doesn't seem to be related to direct visible background load (but i wasn't able yet to get a top up during such a stall) I don't remember these stalls from the non Entitlement kernel. They only happen very rarely so it could be something unrelated too. I know the report is probably too vague to be useful. -Andi
