Looking at putting together a new machine with a pair of
fast SATA disks (WD raptors), and wanted to get a rough
feel for the optimal filesystem blocksize, type, and
raidframe stripe size, plus what the speed increase would
be compared to an older IDE disk and another SATA disk.
So, one small perl script which calls newfs on a filesystem,
mounts, extracts Openoffice distfile, umounts, remounts
removes, and then umounts later...
Timings included for an older IDE disk (ST315320A), standard
SATA disk (ST3200822AS), the two fast raptors (WD740GD),
and of course two variations on raidframe RAID1 on top of
the two raptors.
In each case the filesystems were tested with 4k-64k
blocksizes, ffs 1 & 2 (O1 and O2), and softdep, no mount
flags, and async.
My conclusion on this was to go with 16 blocksizes, ffsv2
(more for the faster fsck), softdep, and raidframe with
128 stripe sizes.
The test system is the latest netbsd-2 on an Athlon64 4000+
in an Asus A8V-deluxe motherboard with 128M of RAM. On some
of the 64k async tests I was able to trigger a lockup. I
need to look at that more.
In case anyone else finds this interesting. Do not place
any value on the fact seconds are displayed to one decimal
place.
