Ditto. Two machines back-to-back 100Mbit full duplex. Private NFS network. Migrating from 3/tcp to 2/udp seems to help alot. Can anyone else help confirm that in general 2/udp is the most dependable way to run if you're not traversing anything slower than 100Mb? I also haven't seen the "I've mounted soft and intr, yet things still hang" behaviour using version 2 and udp. Any consensus on that?
