Poor Fileserver Performance with Multiple Accesses
A confession, its just a dual-IDE software-raid-0 (each drive is the
single master on its chain), my personal media server. Still,
performance is absolutely perposterous. Debian testing with 2.6(.6-mm2)
kernel. hdparm speed testing is ok, about what i'd expect, but anything
where there's multiple accesses is really pathetic: transfers run in
three second spurts before dying and starting back up again from zero.
its really quite pathetic.
I often have an instance or two of XMMS running remotely. I have the
graphical refresh set low, ~6 fps, i have a 2000ms buffer and 100ms
polling. and mmap enabled. still, if i do a samba copy to or from the
drive while music is playing, a little after two seconds it starts
stalling out something horrible.
samba is a very bare configruation: no real performance tuning.
i just tried doing a basic cp. same results. xmms stutters heavily
once or twice a second.
please help
