Heh that scheduler thing again... and unfortunately Col appearing to feel hurt while I am think that Ingo is honest on his offer on collaboration...
While it makes fun playing with that numbers and indeed experiencing subjectively a more fluid deskopt how about just a
echo "This is a f* desktop!" > /proc/sys/kernel/sched_workload
Or to say it in other words: The Linux kernel should not require me to fine-tune three or more values to have the scheduler act in a way that matches my workload.
I am willing to test stuff on my work thinkpad and my Amarok thinkpad in order to help improving with that.
