This is perl, v5.8.8 built for x86_64-linux-thread-multi :)

In 2009, it was, per day, 516 messages accepted for distribution, and 
around 450 000 distributed messages (I add this last information because 
that's what bulk.pl does; distributing messages).

See attached graph. It is our memory consumption for the last year. 
Sympa 6.0 was installed on the server since last may.
It looks like our work on wwsympa memory optimization did bear fruits.
Actually, bulk.pl doesn't appear on this graph, which is bad. A bulk.pl 
process takes roughly 350 MB. If it forks into three processes, you can 
then reach a GB of used memory. Again: the additionnal bulk.pl will die 
after some time without sending messages. You can also tweak the max 
number of bulk.pl processes, the conditions under which it will fork and 
the time it will stay alive. see:

Bad example... I just installed the latest alpha (future 6.1 beta) last 
week. So it is only running since one week.
