One more drawback that caused me to stop using them in significant
fashion... NFS is CPU intensive when used in an IFS I/O heavy scenario
(i.e. mapping Node.js runtime).  I don't have a full understanding of how
NFS works under the covers but suffice to say I learned to not put it in a
similar camp of the Linux "mount" command (which is how I was using it,
right or wrong).
