[Freeswitch-users] "Upgrade" from 1.3b to 1.2stable caused higher cpu usage

Wed Sep 25 01:12:07 MSD 2013

Hi Anthony,
 I was looking into doing the bisect but can't get it working with the 1.3.13 branch? This is also the first time I'm using git bisect so that could be the issue… Any pointers?

These servers was installed with version FreeSWITCH Version 1.3.13b+git~20130215T194756Z~9733740cab (git 9733740 2013-02-15 19:47:56Z) and they have been running fine with 250% cpu (out of 2400%), load average hits 3 at peak.

This servers cpu is at 800-900% and load average hits 10 when the server runs with 1.2.12, if we rollback cpu goes back to old 2-300%.. Call quality is still ok but I feel we have less room for more load and upgrading should normally improve performance not decrees performance. Just as an experiment I also tried to install latest 1.4 thinking this might have been something in the 1.2 branch but 1.4 acts the exact same.
