In various performance tests we have found proto=tcp to be uniformly a Good Thing. I'd vote for that to be default in general, but perhaps there is an AMD-specific reason for UDP; I can't imagine what that would be, though. --ckg On Fri, Aug 31, 2001 at 01:03:46PM -0700, John Polstra wrote: > I

Howdy! I am interested in tuning UDP for NFS over a 100Mbs LAN. Specifically, to tune UDP, what are guidelines/restrictions for setting the sysclt variables net.inet.udp.maxdgram net.inet.udp.recvspace I assume that increasing both of these
