boot Your kernel with "divider=10 nohz=off" options :)
Recent kernels are tickless which basically causes all freeswitch timers/sleeps to fire at requested microsecond intervals. With nohz kernels You get hundred times more system calls with freeswitch :(
Like Jason, I am also interested to know why the tickless kernel causes the timers to generate so much more load. I can't find anything documented anywhere, really, about the issue — and this thread is the only thing Google turns up on the topic. I am looking to move my SIP system to FreeSwitch some time soon, if I can, but I would love to know why nohz is so hostile to FreeSwitch before I do, if possible. Regards, Daniel
