CPU load balance or one task domination under linux-2.6.7-ruby-s77

[Aivils <ai...@un...>]

Hi All!

	I try multiple local user linux box.
All 2.6.XX kernel versions from 2.6.0 up to 2.6.7 do one task domination.
I applay before staircase 7 and now staircase 7.7

Anyway if two users run games simultaneous, then one game allways
dominate.
If i set "nice -n +1 game-bin"  for each user , then both games
became choppy, because lost priority against system tasks.

Second phenomen - tuxracer under 2.4.26 take 1%-3% CPU time,
but under 2.6.7-s77 it eat 80%. As result i cannot test thiny games
simultaneous, because thiny goes fat and choppy.

Does know anybody is this phenomen realy depended from task
scheduler alghoritm?

May be that is system call queue?
