<p>Hi,</p>

<p>&nbsp;</p>

<p>I am currently doing some characterization testing to figure
out the limitations of my freeswitch server. I have tried both with SIPP and by
driving SIP calls</p>

<p>between 2 Freeswitch through mod_event_socket. I get similar
results both ways and I am suspicious of the results I get.</p>

<p>&nbsp;</p>

<p>Basically, whenever I try to launch calls with SIPP at a
rate superior than 8 cps, it seems like calls are being stacked. The response
time for a call between</p>

<p>the "invite" and the corresponding "200 OK"
keeps increasing as long as calls are being made which slows down the
processing speed until the average </p>

<p>CPS gets around 8 cps.</p>

<p>&nbsp;</p>

<p>My setup is : </p>

<p>1 Dual-Core AMD Opteron(tm) Processor 8216 @ 2.4 GHz</p>

<p>4 GB of RAM</p>

<p>Gigabit NIC</p>

<p>Centos 5</p>

<p>FreeSwitch Version 1.0.trunk (8911M)</p>

<p>&nbsp;</p>

<p>I think that my setup is underperforming and that it might
be related to some missing configuration tweaks. I already adjusted the ulimit
to the</p>

<p>recommended settings in the wiki for maximum performance. I
was wondering if there might be something else, that I'm still missing.</p>

<p>&nbsp;</p>

<p>Would any of you have an idea of what might be holding back
my setup ?</p>

<p>&nbsp;</p>

<p>Thanks !</p>

<p>&nbsp;</p>

<p>PG</p>

<p>&nbsp;</p>

<p>P.S. I gathered a bunch of information that I thought could
be useful.</p>

<p>&nbsp;</p>

<p>Freeswitch performance settings In switch.conf.xml</p>
