I suspect most of the time to zone is spent uncompressing that
data being sent from the server. This was also the case for
Diablo - copying the CD to hard disk only helped to a point,
but upgrading the CPU helped tremendously.

FWIW, on my cable modem and 450 Celeron (OC) with 128MB RAM,
it takes from 15-35 seconds to zone.

However, comparing ping times for the same route (assuming
relatively constant Internet traffic) using two different
modems *will* tell you the relative performance of those two
modems, since the times across all the other hops should stay
roughly the same.
