That depends on what you're doing. If you're running some digital signage display or whatever, no one cares about a missing display frame or whatever. But if you're running a car's HUD or, worse, its steering system, you absolutely need the execution time guarantees or your code won't make it past certification.

I'm not saying it's not an important space, because it is. But the majority of use cases are not that latency-sensitive. And if you're not that latency-sensitive, it's not obvious that microkernels like SeL4 and QNX are faster than Linux.

And the goalpost moves again.

Could just as well be read as the position of the goalpost gets more precisely specified for each question. The original "performance" was quite ambiguous; this is just a final specification of what was meant by the word.
