Yes, that's the proper default. You could try setting steal_thresh to 1. I
noticed a problem with building ports on an 8 core Xeon system while 8
distributed.net crunchers were running. The port build would proceed
incredibly slowly, steal_thresh=1 helped a little bit. It might not make up
the 5% gap you're seeing though. During early ULE2/3 testing the other
variables Jeff recommended trying were sched.pick_pri (which I never saw
effect from), sched_tryself and sched.balance. They're all bools IIRC. Since
this workload is a bit different from any of mine it would be worthwhile to
try those variables.
Thanks for the information. Setting sched_tryself to 0 improved things
slightly. sched.balance didn't seem to help. I'm trying to
increase/decrease the balance_interval to see if that helps.
