It depends on your network load.
If your NFS server is connected via 100 mbit Ethernet, but your
Internet used bandwidth is significantly below that, it is unlikely
that NFS is a bootleneck. The NFS data volume will be of the same
order of magnitude as the volume your http servers serve collectively
to the Internet.
Adding lots of RAM to each real server will help, because all frequent
files will be buffered in RAM and create no NFS traffic.
I am planning to NFS mount all web docs and cgi directories
for a set of 4 real servers.
If you decide to keep the web content local on each server,
use rsync to keep it synchronized.
It is higly efficient and convenient.
