[PVFS-users] PVFS API Performance with Multiple Processes

[Nathan Poznick]

Thus spake pvfstester at fastmail.com.au:

It's a little unclear - are these 3 machines acting as both servers and
clients?  If so, then performance can certainly be affected in new and
interesting ways.  Historically, we see slightly higher performance when
using the PVFS API than going through the VFS.
