We’re running Asterisk 17 on a 20-core Xenon Ubuntu server, exclusively as a voice conference Stasis application. All incoming calls are SIP trunk calls. We seem to be getting roughly 1 caller for each percentage point of CPU power (using htop we can see that threads are being correctly distributed over all cores).
How best to tune the server for more callers? If anyone does this for a living, we’d be interested in talking with them.
