I wish I am posting the message to the right place. I am just curious
what's the most important reason to choose UDP instead of TCP. And when
some error happens, will NFS do retransmission ? thanks.

You need to familiarize yourself with the history of NFS.
Who, when, and in what kind of environment did invent NFS.
(Sun, late 1980es, machines with _very_ low power compared
to todays standards, and very slow networks!)
Doing NFS over TCP has been a lot more recent development.
Yes, when errors (like UDP datagram loss -> response timeout)
occur, NFS must do retrying / other error processing.

NFS also supports TCP, just config it to use TCP.

IIRC only NFS client does. Or is both client and server RPC over TCP
already working?
