rpcinfo -p remote_host

showmount -e remote_host

rw,soft,intr,rsize=8192,wsize=8192,udp,nfsvers=3
# soft - prevents nfs mount from blocking
# udp - I prefer udp on a stable lan env
# intr - allow signals to interrupt file operations
# rsize / wsize - this should match with the MTU size, tho I've seen good performance on a much higher value
# nfsvers - this should match with whatever the remote server is capable of
# retrans - retransmit a request before performing recovery, defaults to 3. after retrans retries, client writes "server not responding" to syslog
