Well, yes... depends on your application, though. Our Hesiod/BIND
servers, on the other hand, are soon going to be upgraded to Alphas,
and it couldn't happen anytime too soon...

Yes, ladies and gentlemen... that is over 20meg of resident memory
used by our BIND/Hesiod database under normal operation. And, it
can't be allowed to swap if you want any performance at all out of the
machine. So, in small installations where Hesiod isn't an issue, this
would probably work great. But, if it's a large installation (we have
three of these machines, plus three nameservers without Hesiod that
get queried mainly by the non-Unix machines on campus [much lighter
load]), you might want a bit more machine than a 386. :-)
