<div>Hi</div><div>I am trying to test performance of kamailio server. I have made some tests on old hardware, that was ok. I found that it can handle around 450 calls per second with authorization.</div><div>CPU utilisation was up to 100%. That testing was OK, because server's CPU utilization was increasing. Now I want to do some test with new hardware and do some comparisons of those two hardware configurations.</div>
<div>I have made some test but i found that it can handle up to 540 calls per second with authorization. But CPU utilisation was only around 8%. When I increased call rate server responded with 404 Not Here and 500 I am terribly busy messages.</div>
<div>I think that it is because of that it is not capable of finding a user location that fast. Can i do something to increase the performacne of this server?</div><div>I am using SIPp testing tool for generating calls. I have registered users manualy with kamctl ul add sipp <a href="http://sip:sipp@192.168.1.1:5060">sip:sipp@192.168.1.1:5060</a> command.</div>
<div>I was using this tutorial: <a href="http://www.troubleshootingwiki.org/OpenSER#Stress_Test_The_SIP_Signaling">http://www.troubleshootingwiki.org/OpenSER#Stress_Test_The_SIP_Signaling</a>. And also i made my own scenarios.</div>
<div>Any suggestion would be usefull.</div><div>Thanks.</div>
