I skimmed through the tests in the benchmark and it seems like they’re testing based on throughput and I didn’t see any tests specifically to measure latency. It would have been really useful to see that.
Was discussed before these (mostly throughput) benchmarks in <a href="https://news.ycombinator.com/item?id=39173229">https://news.ycombinator.com/item?id=39173229</a>

If the system could detect when low latency is important they could get away with a single kernel. Or even simply enable low latency by default for the desktop version of ubuntu.
