some new interesting results with 2.5.42:
http://spunk.dnsalias.org/latencytest/2.5.42/2x256.html
overall much worse, *but* greatly reduced latency peaks (max. 6 ms) as
compared to 2.5.41:
http://spunk.dnsalias.org/latencytest/2.5.41/2x256.html
here the peaks easily reach 13 ms.
Rather depends on the filesystem. ext3 does its own write scheduling,
and does stuff inside lock_kernel(). It needs a couple of scheduling
points I guess.
I'd expect ext2 to work OK with preemption, but nobody has really
looked yet. Unless you're using ftruncate() (grr.)
