> Combine that with the fact that they chose to implement the scheduler in Java instead of C(++) and you're set for performance problems.

Ah yes, the argument from the 1990s. It would make sense to understand where the JVM and its compiler are these days before making incorrect statements about performance.

From your link:

This is utterly false.

So how do you implement a TCP socket?

I have always had to do synchronized(something) { socketInputStream.read(); }

And the dude himself says that reading from a socket is a problem if you listen to the interview.

Something tells me you don't know much about programming in Java. Just look up any tutorial showing how to use NIO (blocking and non-blocking).

Synchronized in this context is pretty nonsensical.
