Interesting results.
It'd be nice to see what difference the changes since .31 have made to these comparisons. In particular, child_runs_first was found to have a substantial negative impact on parallel compiles, and has been turned off. The reduction of sched_latency has a rather large effect on worst case latency for CPU hogs, so will likely affect some results markedly.
Hohum, back to the grindstone.
