- 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*.
