<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">you might want to look into the code to see if there is maybe some condition where it not send out a SAR message.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">Maybe also investigating the size of the difference is worthwhile as well. It might be a particular bug, but is hard to say without going more into the details. If you enable debug log
level for Kamailio you will get more information about the internal processing from many modules and the core.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">Hi All,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I am experimenting with Kamailio 5.3.3 as an IMS and I am trying to do load tests<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I am using SIPp to generate SIP.REGISTER and MariaDB and a DIAMETER tool ( seagull)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">For now I achieved registrations with "speed" 200 per/sec.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">When I send SIP.REGISTER faster(let's say 500 per/sec) I see some SARs missing, not sent at all.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I start debugging and found that cxdx_send_sar is responsible to creating SAR message. I put my debug message in it.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The strange thing: there is a mismatch of my debug message (cxdx_send_sar invocation) and real SAR send over the network.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">What is the thing I missing ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Is there anything else responsible for SAR creating except cxdx_send_sar ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Did someone made similar tests ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">my test machine is Centos 7 with 3.10.0 <o:p>
</o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">16G RAM<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">During this tests I see kamailio very low CPU usage, even when I push it with 500/sec<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The biggest CPU load is in MariaDB, but I do not have issues with UAR and MAR<o:p></o:p></span></p>
