   Description
     Adds soft real-time prioritization to the controller server to better ensure resources to time sensitive portions of the codebase. This will set the controller's execution thread to a higher priority than the rest of the system (``90``) to meet scheduling deadlines to have less missed loop rates. To use this feature, you use set the following inside of ``/etc/security/limits.conf`` to give userspace access to elevated prioritization permissions: ``<username> soft rtprio 99 <username> hard rtprio 99``
