Hi Jerry,<br>
<br>
If I recall correctly, there was a talk at an AstriCon or a web page <br>
somewhere that I came across at one point (I'm having a hard time <br>
finding it now) that dove in fairly deep into Asterisk performance <br>
related to multiple cores.<br>
<br>
And if I recall correctly, the conclusion was that the drop-off was <br>
around 8-12 cores -- and beyond that the extra cores aren't doing much <br>
other than helping schedule work and you can't really get more <br>
concurrent calls by adding more cores.<br>
<br>
Someone who is a bit more well-versed in large-machine performance with <br>
Asterisk can certainly chime in here, but from what I gather, throwing <br>
40 cores at a single Asterisk instance is not the magic bullet to <br>
support a massive number of calls.<br>
<br>
