PVM Users:

Greetings; I have a question about your experience with PVM.  We are getting
an HP and have two possible locations for installing it.  One is in the
same room as our other HP; the other is in a different room but in the
same building.  In the latter case, the ethernet cable goes through a
couple of switchboards, but it stays in the same building; so it 
wouldn't go through any gateways.  Would the message passing speed
be perceptibly lower in the latter case?  I personally suspect it
would be, for the longer length of the cable if for nothing else.

Thanks for your time.
