I haven't noticed any problems with response time on that machine. The
current load average reported by tload is:
0.01, 0.04, 0.01

It needs a kernel with ATM enabled, some kernel modules which I got from
http://www.linuxdsl.co.uk/ and it needs a patched version of ppp, which
they provide as a binary, but which I built from source according to the
instructions at http://www.wlug.org.nz/LinuxPPPoA

It's a pc with a Duron processor, 512Mb memory and a 40Gb IDE disk; it's
using shorewall as a firewall. It runs my incoming mailserver, with
MailScanner, spamassassin and clamav to filter spam and viruses (using
the daemon versions of both) and Cyrus IMAP server to receive mail for
users on other machines. It's also got an Apache server running, but
that has only 1 static page to serve, together with sugarplum (to poison
spam address harvesters). It is doing a bit more than my previous
gateway machine, but that was a 486 with only 64Mb memory, which tended
to choke up when too much mail came in at once (and that was just
sendmail, with no filtering). I would guess that a P60 would be fine as
gateway and firewall, but I would pass email through to another machine
for filtering.
