Recently I'm noticing bad behavior of the CPU scheduler on my T61 (2GB, C2D)
It looks like Linux concentrates all running tasks on one CPU and the
second cpu is sleeping.
With recent changes to DRI - glxgears went up to 840FPS but also takes
100% (with Xorg) and when I run 'while :; do true; done' loop in
parallel frame rate drops to 300FPS.
But as I have C2D CPU I would expect that there should be no such
Xosview shows that only one CPU is fully loaded.
Here are my .config scheduler options:
# CONFIG_GROUP_SCHED is not set
# CONFIG_SCHED_MC is not set
# CONFIG_NET_SCHED is not set
Am I missing something?
