Mmmh... it isnt insane.
Servers allocate memory to keep track of nicks, addresses, real names, channel
modes (bans, ops) and so on. They even hold a copy of the away message!
There's an option of the STATS command (or was it the INFO command?? I
dont have the RFC 1459 at hand) which will tell you how much memory the server
is currently using for each type of information it stores in RAM.
If you consider that there are *thousands* of users on IRC, it's obvious
that inetd is going to eat MBYTES of memory.

Talking about servers and 68020, the main italian server (irc.ccii.unipi.it)
is a 68020 Sun with 32MB of RAM running SunOS4. Due to a limitation of the OS,
it can accept max 200 clients on it.
During the day it's often split because the link to the rest of europe it's
painfully SLOOOOOOOWWWWWW. But late at night (when the link gets better but
the traffic on IRC increases due to the american users) it handles 100-150
connected clients plus all the thousands clients from other servers.
Oh, I almost forgot: it also runs the multicasting software -- for video-
conferencing purposes :). And it also runs X on the 24 bit framebuffer :)))).

Despite all of this, it runs SMOOTHLY. As I said, problems arise only during
the day, but they're caused by *THE NETWORK*.
