;-)

Its a:
- Pentium II (Deschutes) 333MHz
- 128mb memory

I'm using it as:
- Mailserver (IMAP, SMTP)
- Webserver (mainly for webmail)
- Newsserver
- Packet Radio station
- VNC server
- Proxy
...


Some system information:

and "top" tells me:

Is it a little bit too much for such a machine? What could be the 
bottleneck? CPU? Memory? Interrupts?

Bye!
