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 :(

After upgrading to the 2.6.29 kernel (the Debian packaged version),

takes up more CPU time than usual, e.g., 7% as reported by top, and
the load
average is high (e.g., 0.87) even when the machine is idle and there
are no
calls in progress. When top is run, FreeSWITCH appears at the start
of the
list.
Is anybody else seeing this? The proportion of CPU time devoted to
system
calls seems higher than it should be.
I would be interested in reports from anyone else who is running
FreeSWITCH
under Linux 2.6.29.1 or equivalent from a distribution.
