[Freeswitch-users] CPU Usage Question

[brian@freeswitch.org]

It's because Sofia used one thread per profile so depending on load you will see one CPU used more.

We have about 1500 concurrent calls on the server.  And, the CPU usage is shown below:

02:06:46 AM  CPU   %user   %nice    %sys %iowait    %irq   %soft  %steal   %idle    intr/s

1) I am wondering whether it is normal that every time when i checked, only CPU 2 always have the highest %iowait (in this case 3.49%).

2) Shoudn't it spread out and balance them to utilize all CPUs evenly?

Thank you.
