[sr-dev] ASYNC module - CPU load

Good morning! In one installation where Kamailio runs in a VMware virtual machine we use Async in a registrar. There's no traffic - only one SIP device registred - but the CPU load goes up. If we change the workers to 1 CPU load goes down, if we set it to 8 CPU load average quickly goes up to 3. If we add a second CPU, nothing changes. Again, with no traffic. The CPU load is directly related to number of workers, but not if they are used or not. My conclusion is that something in the Async module is causing CPU load regardless of traffic - primarily depending on the number of workers. I don't think that's the correct behaviour ;-) Kamailio 4.2.0 Cheers, /O
