this seems truthy but isn't in practice. a lot of work, my perf optimization team @ redpanda does (yes we have a full team chasing tail latencies) is spent on CPU optimization, debouncing, amortizing costs, metadata lookups, hash tables, profilers, etc. so there is a lot of additional work after the IO layer which a decent async eventing thing can get you to get good perf.

What I mean to say is that in my experience the time spent round-tripping to Kafka is more than the time it takes Kafka to do whatever I'm asking it to do. So at least for my use-cases a faster Kafka would be of no benefit.

Now if it means I can run fewer smaller brokers that's awesome.
