Lucas in Absolute FeeBSD , 2nd Edition , ( ISBN : 978-1-59327-151-0 ) , is suggesting the following ( p. 248 ) : In client ( mount , or , fstab ) , use options ( -o tcp , intr , soft , -w=32768 , -r=32768 ) tcp option will request a TCP mount instead of UDP mount , because FreeBSD NFS defaults to running over UDF .
