been reading / work with elixir and was interested in finding out the cause of high cpu usage.
TLDR: BEAM VM uses busy waiting under the hood to achieve fast response time when dealing with requests. you can disable it by setting a few options in the VM.
Edit: Interesting thing here is that there's no significant latency difference when toggling busy/wait, so not sure why that's the default.
