Depends on the NIC.  If your running 100MBS Ether and put in 1GBS Ether or
fiber, it would make a difference.

I don't understand.  What interface other than a NIC are you now
using to go "over the Internet"?  Or do you mean that you want an
_extra_ IP address so that the web servers don't have to compete for
the bandwidth?  In that case, sure, you'll probably get a minor
performance increase, depending on your current network traffic.

In the future this spectacle of the middle classes shocking the avant-
