NFS over TCP is a performance hit on a lan compared to NFS over UDP. If you have hosts mounting stuff over a wan link, then TCP/NFS does offer a bit of added stability.
I hate to beat a dead horse but...
I don't see why NFS over TCP has to be a performance hit. Aren't there optmizations that could be made that take advantage of the additional semantics that can be gleaned from TCP? ie. since you know where the request came from, isn't there slightly less work to do WRT processing the incoming RPC? I thought I saw someone from Sun (Hal Stern?) or possibly Andy Watson (before he came to NetApp) once say that he saw an implementation that did this.
Or is the problem with the NFS clients?
