Nevertheless I was going to repeat the performance measurements on a
recent kernel but haven't gotten around to that yet because the
measurements need to be performed with CONFIG_PREEMPT_RT_FULL to
be reliable (a vanilla kernel is too jittery), so I have to create
a new branch with RT patches on the test machine, which is fairly
involved and time consuming.

I assume you will then mainline the changes, so you don't need to do
it again? That is the problem with doing development work on a dead
kernel.

I think the limitation is outside of his control as not all of the RT
patches are in mainline yet.

So how shall we proceed here?

Some basic measurement results are here, for the reference [1].
