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.<br>

<div><div>I have 2 identical Dell PowerEdge 1950 servers running FreeSWITCH Version 1.0.4 (exported) with only one thing difference which is the first one is running with -hp enabled; however, I have noticed that the one with -hp option consumed double in memory usage than the other one. </div>
