It all depends on the system setup.  With a good portion of RAM, a clear
connection, and quick access to a DNS server, it should be fairly smooth.

A local DNS server will speed things up.

This process is handled by the MTA.  mailman hands off the mail to sendmail
and then sendmail processes the queue, usually host at a time.  Which means
if one host isnt' resolving, the rest of the queue will have to wait til
that host timesout.
