I ran iozone and bonnie++ on NetBSD, FreeBSD and Linux using
ffs, ufs2, lfs, ext3fs and reiserfs.  Results are avilable
at <>.

Results are something like below.  Using RAID 5 across 4
WD800AB drives.

Linux software RAID5 25MB/s
NetBSD software RAID5 10MB/s
NetBSD hardware RAID5 25MB/s

Linux software RAID5 45MB/s
NetBSD software RAID5 33MB/s
NetBSD hardware RAID5 30MB/s
