Why is running NFS over IP better that running NFS over UDP?
 
It's not. Your question doesn't make sense. UDP uses IP. In fact the two basic protocols running on IP are called TCP/IP and UDP/IP. So, your question can't be answered as written.

If you're asking about TCP/IP vs UDP/IP, the short answer is that TCP is much more secure (data wise), but UDP is faster. TCP/IP has a lot of overhead to make sure the data gets to where it needs to be intact. UDP/IP just kind of blindly shoots the data and packets can get lost through misdirection or colision, so the application has to deal with lost data and retransmissions. UDP/IP is very fast though because it doesn't have all that overhead confirming that the data made it.
 
I had many problems using UDP over a WAN, lots of "nfs server not responding, trying again" messages. UDP works fine on a local network, but if latency is high I'd recommend switching to TCP. Annihilannic.
