<div>I believe priority works in a similar way to metric (i.e. lower comes first), so <span style="font-size:10pt">-20 (most favorable scheduling) to +19 (least favorable scheduling).</span></div>

<div>
<p class="MsoNormal">I’m trying to set the priority on a new FreeSWITCH installation built from master on Debian 8 running on bare metal. It is currently running at “very low” priority according to Resource Monitor in the GUI and ‘top’ reports FS is running
at priority = -2 (that’s negative two) and nice = 19</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">So with the way FreeSWITCH is now launched by systemd is it considered a service or a user application that is simply run in the background?
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">This affects how systemd treats its control groups and priority and how I will go about troubleshooting this.</p>
<p class="MsoNormal"><br>
Thanks.</p>
