I didn't miss 5 revisions, I'll just stick to using my internal
numbering for releases.
This one has a few changes. Children now get a priority boost
on fork, and parents retain more priority after forking a child,
however exiting CPU hogs will now penalise parents a bit.
Timeslice scaling was tweaked a bit. Oh and remember raising X's
priority should _help_ interactivity with this patch, and IMO is
not an unreasonable thing to be doing.
Please test. I'm not getting enough feedback!
Well, it's actually a bit faster than either mainline or your previous
rev whilst running SDET:
SDET 128 (see disclaimer)
Throughput Std. Dev
2.6.0-test4 100.0% 0.3%
2.6.0-test4-nick 102.9% 0.3%
2.6.0-test4-nick7a 105.1% 0.5%
But kernbench is significantly slower. The increase in sys time has dropped from last time, but user time is up.
Kernbench: (make -j vmlinux, maximal tasks)
