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

Subject: [Freeswitch-users] CPU Usage Question
To: "FREESWITCH-USERS MAILING LIST" <freeswitch-users@lists.freeswitch.org>

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
02:06:46 AM all 0.06 0.00 0.03 0.44 0.00 0.00 0.00 99.47 1028.25
02:06:46 AM 0 0.08 0.03 0.03 0.01 0.00 0.01 0.00 99.84 1007.07

02:06:46 AM 7 0.05 0.00 0.02 0.01 0.00 0.00 0.00 99.93 0.00

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.
