 For optimal performance the server is implemented in low-level C and makes use of several Linux-specific realtime features.
 The primary design goal was to make the behaviour of the system as deterministic as possible.
 
-Therefore, it's advisable to run the server component on a [RT_PREEMPT](https://rt.wiki.kernel.org/index.php/CONFIG_PREEMPT_RT_Patch) patched version of Linux. In our environment, we use Fedora-based distribution which has been stripped to the bare minimum (no GUI, only a few background processes).

 The server is a multi-threaded application.

 ## Operating System and Kernel
 
 For minimum latency several kernel and driver settings can be optimized.
