It all depends on what your application does with that network and how beefy your nodes are.
For instance, if you were to run something like Amber (molecular dynamics) over an office
LAN, I can pretty much guarantee that you will not win any office popularity polls. It
simply saturates the network. If your nodes are reasonably slow you might be better,
relatively, as you might have reduced network traffic because you nodes are spending
more time thinking. I wouldn't depend on it.
On the other hand, you have to consider what those pesky co-workers are doing to YOUR
network. ;-) Use of M$ Outlook and streaming mp3's off fileservers, to mention a couple,
will cut into YOUR bandwidth causing performance problems.
Just my $0.02 worth.
