That's a pretty impressive read speed...was that using dd? What command options
were you using?

So you created a single /usr rather than separate /usr/, /usr/home, /usr/ports
etc as described on your blog? Are there any advantages to creating separate
file systems with zfs? With my current server I just have a /usr/ and /var
(plus a few storage directories).
