Load balancing appears to be badly broken in this version. When I
started 4 hard spinners on my 2 CPU machine one ended up on one CPU
and the other 3 on the other CPU and they stayed there.
hm, i cannot reproduce this on 4 different SMP boxen, trying various
combinations of SCHED_SMT/MC
You may need to try more than once. Testing load balancing can be a
pain as there's always a possibility you'll get a good result just by
chance. I.e. you need a bunch of good results to say it's OK but only
one bad result to say it's broken. This makes testing load balancing a
pain.
and other .config options that might make a
difference to balancing. Could you send me your .config?
