[Freeswitch-users] Freeswitch Performance Testing

[Juan Backson]

Hi,

We are running some stress tests  again  freeswitch  using sipp.

At 100 concurrent call, Freeswitch starts to throw out some strange error
messages:

Artoo reduces the max sessions to 328 thus, saving the switch from certain
doom.

Last Error: Aborting call on unexpected message for Call-Id '3143-6125 at 1...


When increasing the number of concurrent calls to several hundreds,
Freeswitch throws the following error:
[CRIT] switch_time.c:394 softtimer_runtime() Over Session Rate of 30!

The test is run on Dual Core Intel P4 3GHz with 1G of RAM.

Is this kind of performance normal for such kind of machine or there are
some OS configs required to enable more concurrent calls?  What kind of
number should I be expecting to get?
