[Freeswitch-users] Different versions, different cpu load

Fri Aug 6 05:13:18 PDT 2010

I cannot see updates/seconds using that command.

I can see following boot params for kernel at /boot/config-2.6.32-21-server:

CONFIG_NO_HZ=y
CONFIG_HZ_100=y
# CONFIG_HZ_250 is not set
# CONFIG_HZ_300 is not set
# CONFIG_HZ_1000 is not set
CONFIG_HZ=100

I have been reading about this task and people recomends using 1000 HZ
instead 100 ¿what do you think?

Centos seems use 1000 by default.
