Re: [sr-dev] ASYNC module - CPU load

I encountered the identical condition inside VirtualBox and remarked upon it to the list previously. This is why I had to revert to rtimer + mqueue + tm_suspend/continue manual approaches. -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry.   Original Message   From: Olle E.

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 _______________________________________________ sr-dev mailing list sr-dev(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
