Hey guys,

I am running FreeBSD 7.0-RELEASE with GENERIC on a AMD XP Athlon 3500+ with
1267 MB of ram, and a GigBit NIC. I am testing out ZFS just for the hell of
it, I know, 32 bit is not suggested and runs badly, but it does what it
needs to do.

I was copying large amounts of data for backup purposes from my MacBook Pro
to the machine over FTP. At the time I was looking around the man page for
zpool, and figured I'd run a zpool scrub just to see how badly it affects
performance. It affects it in that it takes down the machine with a dump.

Out of curiosity, have you done any tuning on this machine?
Specifically some of the stuff mentioned on the wiki?
