Internet Gateway server load.

[Raphaël RIGNIER <raphael@rignier.com>]

Hello list,

Here are my server's specs :
- HP9000 L 1000 Class
-PA-RISC 800 350 MHz
- 512 Mo RAM
- 2*9Go + 1*36Go SCSI Disc

It is used with Debian sarge in a DMZ as Internet gateway.

The services running on it :
- apache 2.0
   * horde3/imp4 webmail (quite slow but few users)
   * sympa mailling list with fastcgi

- mail gateway
   * postfix
   * perdition (imap proxy)

- bind9 (public and caching name server)

- http proxy
   * squid
   * squidGuard

- intel386 sid Debian mirror (Http)

It serves 20 stations on LAN with Windows XP/Linux. There will be soon 
70 more!!

The uptime is : 10:42:13 up 171 days, 18:14,  0 users,  load average: 
0.13, 0.03, 0.01
Do you think it would survive with 70 more stations?
Should I upgrade to etch?

Thank you for suggestions.

Raphael.
