1 million tcp connections with vertx / kotlin

Nothing special other than having to tune Linux

Jvm is very optimized, so it's actually something not that non-special.

That is not totally true, This is a mix of 2 things, using the JVM (which like you said is being tuned and optimized for heavy loads) + using a true asynchronous and reactive programming (and IO) model built on great technologies such as (in this specific case: Kotlin, Eclipse Vert.x and Netty).

As an experiment if you would pick another random set of libraries (imagine a servlet container) achieving the same results would not be so trivial, see for example:

And observe that Eclipse Vert.x is on the top for these reasons while other JVM frameworks are far behind.

That's why I used not two times. I meant that it IS special, sorry for confusion, I'm not a native speaker.
