Note, the -rt kernels _always_ run slower than a non-rt kernel.  Real
time is not "faster", it is only "deterministic".  And it achieves this
goal at the expense of performance, which is the only way it can be
done.

So I recommend just trying the "normal" kernel instead, odds are it will
work just fine for you, unless you have some _very_ specific max-bound
latency issues.
