I've got a web page up now on my home machine which shows data from schedstats across the various flavors of 2.6.4 and 2.6.5-rc2 under load from kernbench, SPECjbb, and SPECdet.

Two things that stand out are that sched-domains tends to call load_balance() less frequently when it is idle and more frequently when it is busy (as compared to the "standard" scheduler.) Another is that even though it moves fewer tasks on average, the sched-domains code shows about half of pull_task()'s work is coming from active_load_balance() ... and that seems wrong. Could these be contributing to what you're seeing?
