also i did some performance tests on openser trunk in order to clear
doubt that has been expressed recently.
with only 4 child processes and several radius/mysql queries per invite,
i was able to achieve 50 new calls per second using sipp including
radius accounting to database of each call. this was on my two years
old laptop and everything was running on the same host. i didn't try
yet how many calls i could have achieved before retransmissions.
i'm satisfied with the result and don't think that there are any
performance issues with openser trunk.
