Looking at Performance Tune my Freeswitch

http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations

Is refers to the following”:

Turn off every module you don't need

Turn presence off in the profiles

libsofia only handles 1 thread per profile, so if that is your bottle neck use more profiles

mod_cdr_csv is slower than mod_xml_cdr

How do I change each one ….any references on Wiki?
