I have found tcptrace, snoop -vv, and the DTrae profile and io providers invaluable for putting together data flow diagrams with latency measurements. There is also some useful information in nfsstat, which might help you better understand activity on the client and server. Hope this helps, - Ryan -- UNIX Administrator http://daemons.net/~matty
