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 -------------- next part -------------- An HTML attachment was scrubbed...

Doesn’t that mean, effectively that you are using the equivalent of 100% of 2.7 CPUs? --Don From: asterisk-users <asterisk-users-bounces at lists.digium.com> On Behalf Of Jerry Geis Sent: Thursday, August 4, 2022 7:33 PM To: Asterisk Users Mailing List - Non-Commercial Discussion <asterisk-users at lists.digium.com> Subject: [asterisk-users] Question on resources I am running Asterisk 13.30.0 40 core CPU (VM) VMware.

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.
