[asterisk-users] Higher CPU usage on 1.6.1 than 1.4?

[Jared Geiger]

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.
