[Freeswitch-users] Strange "timer_test" result

Wed Mar 28 17:31:34 MSD 2012

I have tried:

1. <param name="enable-clock-nanosleep" value="false"/>
2. "heavy-timer" cmd line param
3. 1+2

In all cases, when the load is high (30% cpu), the test_timer result shows
very irregular timings.

Now I have started FS with mod_posix_timer and until now it works fine and
also the test_timer result is acceptable:

http://pastebin.freeswitch.org/18763

so for me the solution is the mod_posix_timer.

Now I'm trying to install a CentOS 6 server to use timerfd.
