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