I think it was in here that I read that you should not use multiple
cpus on the bordermanager box.. but i forget exactly why? i think
it was to due with NAT.

if the problem was with nat, would I be able to use a multiple cpu box

when just using BM for proxy/cache?
we are going to move our firewall services to a pix box hopefully
before the end of summer.

also, would two cpu's benefit the proxy? what about if surfcontrol
was used on the same box as the content filter?

we have approximately 3000 machines going through the BM server,
99.9% via the proxy.
