Hello,
I have fish-fillets game ported to linux. Under 2.6.9-rc1-bk9 it eats up to 10%
with normal speed of game and up to 40% with fast mode.
Under 2.6.9-rc1-mm4 it eats up to 40% with normal speed of game and cpu is too
slow for fast mode.
Any ideas?
For both kernels I use almost the same .config.

Yup. You've just discovered a difference between the nicksched and the
"stock" CPU scheduler, it seems. ;-)

Humm, could this explain why, when I was running amflush this morning
after my journalling failure and subsequent reboot, that the data
being copied from /dev/hda7 to /dev/hdb2 was moving at the grand
total of about 40k to 50k/second instead of the >20MB/sec I expected?
