I haven't seen any authoritative replies to your message, so here's my
guess:

Don't worry about the idle times...  My machine showed pretty
comparable web and console idle times.  Hmmm...strike that...just
looked again, now I'm seeing numbers similar to what you were seeing. 
May have something to do with what is happening...such as the web
server processing the display requests.  I'm not sure if GB hits the
floppy durring that part of the web status update (it certainly hits
the floppy for other things durring the web display), if it does, this
would fully explain the processor idle time, or lack of when doing the
web page update.

You didn't say how fast your internet connection was, but from what I
have seen, a 486/66 with a pair of good ISA NICs can pump several
times T1 speed (granted, with fewer workstations than you have).  The
actual numbers I have seen are so absurd, I don't really believe them,
but I will vouch for the three times T1 speed.  Unless you have either
one heck of a fast internet connection or are doing something unusual
or have some very inefficient NICs, I think that P100 will do very
nicely (and if you are running bad NICs, change those, not your
processor!).

Look at your peak transfer speeds, and compare that to the theoretical
link speeds.  Odds are, you are doing just fine...

Nick.
