Sergey, that's not a problem, is how FS works. That load on the CPU when idle is actually not important. Is just the minimum, like in a carburettor. If you put it under load, you will see that there will need some serious load (many calls) to have it ramp up the cpu usage. -giovanni On Tue, Mar 2, 2010 at 7:16 PM, Sergey Okhapkin <sos@sokhapkin.dyndns.org> wrote:
I see the same problem on 4 absolutely different boxes with different linux kernels.

Well, there you go. your box is having a hard time doing a simple 1ms sleep in a loop for the centralized core timer.
It's either your kernel or your box. My box and every box I have do not have that problem so you may want to consider a new one.
FreeSWITCH is FREE so give it a good home.
The good news is, you can make upwards of 1500 calls on that same 2% of cpu usage.

ps -LlFm -p `pidof freeswitch`
That shows you CPU usage per FreeSWITCH thread
Then
pstack `pidof freeswitch`
That shows the stack trace of every FreeSWITCH thread and then you can
find
exactly what is doing.
