The mailing list for listmasters using Sympa

[David Verdin <address@concealed>]

Hi Paul,

Well, we did some improvements on the memory usage of Sympa for the 5.4 
version. Mainly on the web interface.
Sympa 6 should not be a major improvement about it. we did not change 
the code with that issue in mind. We were more focused on performances 
than on memory usage. though they can be linked.

Sympa 6 can be an improvment, depending on how your previous install of 
Sympa was configured. Here's how:

There is a new daemon called bulk.pl which a small script devoted only 
to message sending. As the messages to be sent are now stored in the 
database, this daemon can be on any machine, provided it can access the 
database and the Sympa donfig file.
On previous versions of Suympa, you could fork Sympa into two processes 
: one received the message, evaluated scenarii and sent service 
messages; the other one was only sending messages it found in the 
"distribute" spool. This second instance of Sympa will vanish with the 
Sympa 6 version.
Shortly, then, all the Sympa processes used to send messages can be 
moved to another machine, if you like. We still use as much memory as 
before, but you can split it on several machines.

And that's about it, regarding memory. I never heard of comparison 
between version but that would be interesting to read. so if you find 
one, please let me know.

Regards,

David
