First I didn't reply here:

We have 603 lists, 12511 users, and 28281 subscriptions. In April I made 
a measurement, in a week the machine received 154 971 mail, and sent out 
1 117 082. The incoming contains spams, bounces, viruses, so Sympa has 
to process fewer. This machine runs the postgres database, clamav and 
amavids-new with spamassassin. I use postfix.

It is a Celeron 1.7Ghz with 512 MB ram and 512 MB swap. Sometimes the 
wwsympa is very slow, and we want to replace the machine, but I think 
so, that 1 GB can be enough for you with a strong CPU.
