Hi!
Yes, I agree!
Best use OS without GUI environment.
but:
1) all the examples I've found use of Debian (FS + Raspberry)
2) but I do not run X, and judging by the processes of unnecessary overhead costs not
3) just starting FS loads the CPU to 100%
4) FS without load is not significant
5) I can try to uninstall the components of desktop OS
http://raspberrypi.stackexchange.com/questions/4745/how-to-uninstall-x-server-and-desktop-manager-when-running-as-headless-server
6) I can try a different operating system specifically for the server
7) RasPBX -- asterisk use Raspbian too

For realtime applications such as voip (Asterisk, FS) it is strongly recommended to use OS without GUI environment.From: Jungle Boogie <jungleboogie0@gmail.com>

Hi Sergey,In place of Raspbian, have you tried PiBang 'server' edition?I want to try FS on this distro since I don't need a GUI._________________________________________________________________________
