Thanks for the recommendation! However, there are a few reasons why Vert.X wasn't considered, the biggest ones being that we're not a Java shop and the service in this blog post isn't HTTP/REST.

While the bandwidth benchmarks are fun to see and write blog posts about, we also care a lot about keeping tail latency at or below 2ms than we do about getting more bandwidth at this point.

Ah yes. The GC latency could be a problem. Java may still be viable with the new ZGC garbage collector. And Vert.X uses Netty underneath which is mostly protocol agnostic.

Still, those issues and not being a Java shop makes Vert.X/Netty likely a bad fit.

Thanks for replying with a well thought out response!
