https://lmax-exchange.github.io/disruptor/#_what_is_the_disr.... Unfortunately IIUC writing this in Go still prevents the spin-locked acceptor thread from achieving the kind of performance you could get in a non-GC language, unless you chose to disable GC, so I'd guess Envoy is still faster.
https://gnet.host/docs/quickstart/ it's nice that you can use this simply though. Envoy is kind of tricky to setup with custom filters, so most of the time it's just a standalone binary.

Disruptor BlockingQueue (by conversant)

Project mention: Is there a technical / scientific / programming name for the Akka threading model based on message exchange between threads? | /r/javahelp | 2023-05-20

My take is that by using Akka (and exchanging messages between threads) there is no need for state synchronizations through locks. Then if you can make your inter-thread queue (i.e. PIPES) lock-free (i.e. Disruptor, Conversant Disruptor, CoralQueue, etc.) you are on for some non-locking ultra-low-latency.
