sympa_msg scans incoming spool ("msg" directory), fetches a message,
processes it and then sleep for a while (1 second by default),
and then repeats.

Check "incoming_max_count" and "bulk_max_count" paramters in sympa.conf.
Increasing these parameters may shorten the delay before fetching messages.

See also the report of a load test.  In this case Sympa could process
simultaneous 40 incoming messages per second with 3 to 4 seconds of
delay on average.
