[Freeswitch-users] Tuning Up Freeswitch

Fri Apr 22 22:02:40 MSD 2011

FreeSwitch is working quite well for me on openSuse 11.4.  I'm actually running it on a default desktop install of openSuse, with no changes to the OS at all other than installing FS and its dependencies.  I'm sustaining 165 concurrent calls with no problems.

Freeswitch is targeted for CentOS 5.3, which in my opinion quite short
sighted for the developers to do this. However with the limited size
of developers and testers, I'm afraid there's not much platforms we
can throughly test and actually say "okay, FS will run flawlessly on X
distro"

However you can always try messing with the CFLAG's mtune option and
see what it produces for you...
