I'll be able to spend some time on this this week (I bet it will not rebase on top of latest without a ton of conflicts). Re flamegraphs etc. I don't have any with async io, but from past efforts, I see too much noise from the execution engine. Mostly what you see in the flame graph is the time spent is in waiting and copying data into read buffers. The benefits from parallelism and from threads not waiting for input are not so obvious. I'll give it another shot and share. -- This is an automated message from the Apache Git Service.
