<div dir="ltr">The original test was done on git master at the date mentioned. The sqlite core.db file was on /run/shm which is a tmpfs on unbuntu 12.04. <br>I will be recompiling from git master and test running with -nosql. <br>
<br>Testing my existing setup with -nosql seems more stable now running at 210CPS for some time (500k calls already passed) with ~35% idle cpu. <br>But the free mem is slowly going down. I will let it run untill the kernel will kill it to see how many calls it can handle. <br>
<br>During my tests i did not run FS with RT priority but according to htop some of the threads are scheduled as RT. <br>My setup is doing bypass-media , thus FS handling only call establishment and teardown on both legs. <br>
