I thought that could be, but I'm not sure.  I left the filesystem idle all 
night, and I still have (from "ps auxww"):
root      3047  4.7 16.7 674668 673444 ?       Ss   Mar07  49:26 
[glusterfsd]
root      3068  4.9  2.5 103072 101584 ?       Ss   Mar07  51:29 
[glusterfs]

Agreed.

Well, I didn't know I could even do a performance translator on the 
server (glusterfsd)! All my performance translator tests are with the 
client spec only.  My server specs only contain storage/posix and 
protocol/server.  Client and server both are running on the same node(s).

Are performance translators recommended/required for both client and 
server processes? Can you do the cluster translators on the server-side, 
too?

Cool beans.

Thanks,
