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. </div>
<div><br></div><div>We wanted to get our Freeswitch onto a stable release and thought 1.2.12 was the most stable version so this is what we installed on one server. 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.</div>
