A typical situation with non -rt systems is that thay can work
very well 99.9% of the time, but not when you are doing some
specific things, e.g.

- having heavy network traffic,
- doing frequent screen updates, changing workspaces, etc.,
- using some hardware devices such as WAN or IR interfaces.

An -rt kernel will be more robust in those cases, and also
gives you the tools to optimize your system by assigning
interrupt handling priorities. The result is that you can
have lower latencies.
