Picked up the trick myself from freebsd-geom some time ago :-) http://lists.freebsd.org/pipermail/freebsd-geom/2007-July/002498.html My Eee PC with a single core N270 is being repaired atm, it suffered a bad BIOS flash so I can't help you with benchmarks until it's back. I don't have access to another Atom CPU unfortunately. /Morgan
