[asterisk-users] Higher CPU usage on 1.6.1 than 1.4?
Hello, We have a customer who upgraded from Asterisk 1.4 to 1.6.1.22 and is now experiencing higher CPU utilization on their server. I can't see anything wrong, so is this just expected with 1.6? Can anyone help explain it? Thanks for any advice. -- David Cunningham, Voisonics http://voisonics.com/ US toll-free: +1 888 842 2720 UK: +44 (0) 20 3298 1642 Australia: +61 (0) 2 8063 9019 -------------- next part -------------- An HTML attachment was scrubbed...

Hi David, When I was testing 1.6.1 for high volume channels, I couldn't get over 1000 channels / 40 CPS without the load average spiking up due to io wait. I switched back to 1.4 and I can go to 3000 channels / 75 CPS with no io wait and a load average in the 1s. It seemed like it was caused by the new timing system in 1.6.1 even though I wasn't proxying media using only SIP. I haven't tried 1.8 yet to see if it handles large call volumes any better. ~Jared On Wed, May 11, 2011 at 8:29 PM, David Cunningham <dcunningham at voisonics.com> wrote:> Hello, > > We have a customer who upgraded from Asterisk 1.4 to 1.6.1.22 and is now > experiencing higher CPU utilization on their server.
