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

[DJB]

Anthony,

Thank you for your clear response.  Based on your recommendation, if I want to route more calls to the first server, should I take off "-hp", or it's better to run with it.  We are running FS for pass-thru traffic with signaling only.

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.

One thing that I forgot to mention, these 2 FreeSWITCH servers are getting calls with load balancing from another switch.  Thus, the traffic type are pretty much identical and both FSs have exactly the same on configuration.  Any suggestion would be appreciated.  Thank you.
