Blackberry Playbook was QNX-based. Performed better than iPad:

Maybe they had some stuff in kernel mode in there. They still show you can start with a microkernel as the baseline then optimize from there retaining the architecture with its benefits in average case or most cases.

The BB10 phones were just as amazing as the Playbook - the UI was oh so smooth and responsive. I'd still be using my Q10 if it had more native apps or better Android compatibility.

One problem with Android is little delays that happen while typing. I thought a QNX-based platform could avoid that if they made sure UI parts were given adequate time slices. Was there any typing lag in those products?

I'd have to try it to say for sure, but it felt like everything was 60 fps all the time. Additionally, the navigation scheme was very quick and efficient, too.
