<p class=MsoNormal style='margin-bottom:12.0pt'>what is the callflow of the
extension you are calling with sipp?<br>
<br>
start by making the target extension just answer and play back a file till you
have it working <br>
and expand it from there.<br>
<br>
you can comment out the manage-presence option in your sip profile to make the
sip a lot less resource intensive.<br>

<p>Hi,<o:p></o:p></p>
<p> <o:p></o:p></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<o:p></o:p></p>
<p>between 2 Freeswitch through mod_event_socket. I get similar results both
ways and I am suspicious of the results I get.<o:p></o:p></p>
<p> <o:p></o:p></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<o:p></o:p></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 <o:p></o:p></p>
<p>CPS gets around 8 cps.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>My setup is : <o:p></o:p></p>
<p>1 Dual-Core AMD Opteron(tm) Processor 8216 @ 2.4 GHz<o:p></o:p></p>
<p>4 GB of RAM<o:p></o:p></p>
<p>Gigabit NIC<o:p></o:p></p>
<p>Centos 5<o:p></o:p></p>
<p>FreeSwitch Version 1.0.trunk (8911M)<o:p></o:p></p>
<p> <o:p></o:p></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<o:p></o:p></p>
<p>recommended settings in the wiki for maximum performance. I was wondering if
there might be something else, that I'm still missing.<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Would any of you have an idea of what might be holding back my setup ?<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>Thanks !<o:p></o:p></p>
