[Freeswitch-users] Question regarding running FreeSWITCH with high priority enabled.

[Anthony Minessale]

One of the properties of -hp is to enable memlockall() which means disable
swapping.  This causes all memory used by FS to be resident permanently and
is much more costly in memory usage.  -hp also uses a RR scheduler runs the
process at a less nice level and increases a few other process ulimits.
This mode is designed for high end usage and uses more resources when idle
with a large payout when scaling to many calls.
