soft is never a good idea, if anything goes wrong on your network the 
application will be given an IO error and data *WILL* be lost, it is much better 
to hang and not lose any data.

Also, rsize=32768,wsize=32768 are decent options, or let it default, you can 
check what option is being used by doing "cat /proc/mounts", almost always the 
defaults will be higher than 8192 or 16384, neither of those options have ever 
been used for NFS tuning except in the case of networking issues causing 
excessive packet loss, and in that case smaller [rw]size is better, but it is 
better to find an fix the networking issue if possible.
