[Freeswitch-users] Does freeswitch forks his processes?

[Peter Steinbach]

I've just stumpled over this:
>Is FreeSWITCH starting with root permissions? It needs this in order to
use the FIFO scheduler and access realtime threads. If not started as
root, this would explain your CPS limitations.

We like to run Freeswitch as a non privileged user, due to security
concerns. So there are drawbacks here compared to running FS as root?
Can we somehow quantify the differences?

Best regards
Peter
