Dmitry Karachentsev commented on IGNITE-3054:
---------------------------------------------

* Increased SSL connection establishing speed, now it's just a bit slower than 
old implementation.
* NIO implementation works slower in general (for client nodes and SSL) that 
causes SPI tests exceed 50 min limit. Working on this.
* SSL still not fully stable, sometimes is thrown "SocketException: Software 
caused connection abort". Investigating.

> Rework client connection handling from thread-per-client to NIO model.

> Currently both servers and clients has the same operational model - 
> thread-per-connection. While being more or less fine for servers, this could 
> be a problem for clients when their total number is too high (e.g. 1000 or 
> even more).
> We should rework client handling model and employ standard NIO technique: one 
> or several acceptor threads + thread pool to server requests.
