The first three columns describe the system & RAID (e.g. RAID10-15 means
RAID10 created from 4 15 kRPM drives), the next three are
write/rewrite/read speed in MB/s, the last two are random files
created/deleted. I hope the mailer doesn't destroy the formatting too

could you compare raw device speed between linux and FreeBSD

it looks like there is driver problem - low linear speed.

ZFS was very good, but not so much when compared to Linux file systems,

ZFS in your benchmart is similar to UFS.
