Somewhat dated now (tests done mid 2007) but here's a
summary of the Bonnie results for a whole bunch of
Linux filesystems plus ZFS on Nexenta (OpenSolaris):

Basically ZFS was OK, but was beaten by one Linux FS
or another in most tests except for block rewrites
and screamed ahead for block reads (very impressive,
double the best Linux filesystem).

But a lot of work has happened since then (2.6.22.1)
so I doubt it's that useful these days..

cheers,
Chris
