• Doesn’t that mean, effectively that you are using the equivalent of 100% of 2.7 CPUs?

  Subject: [asterisk-users] Question on resources

  I am running Asterisk 13.30.0

  40 core CPU (VM) VMware.

  CentOS 7

  32 G ram

  10G vmx network

  Should be plenty of room for anything…

  Yes asterisk is running 270% CPU…

  Is it not taking advantage of the 40 cores ?

  I am bring around 300 SIP endpoints in a muted audio conference (so one way) and this spikes up the CPU to 270%.

  Is there something I dont have set right to take advantage to the resourses?

  Thanks

  Jerry

  What type of conference? Is it meetme or confbridge?

  AFAIK meetme is working on a single thread…

  HTH,

• Hi Jerry,

  If I recall correctly, there was a talk at an AstriCon or a web page somewhere that I came across at one point (I’m having a hard time finding it now) that dove in fairly deep into Asterisk performance related to multiple cores.

  And if I recall correctly, the conclusion was that the drop-off was around 8-12 cores — and beyond that the extra cores aren’t doing much other than helping schedule work and you can’t really get more concurrent calls by adding more cores.

  Someone who is a bit more well-versed in large-machine performance with Asterisk can certainly chime in here, but from what I gather, throwing
  40 cores at a single Asterisk instance is not the magic bullet to support a massive number of calls.
