I've had this same problem. I did notice that I was getting a *TON* of
error messages on the console when access ZFS from a remote Linux
client over NFS. Eventually, it slowed to a crawl and died. I'm in the
process of rebuilding my system so I can't tell you details of the
messages, but you may want to tail -f /var/log/messages.
