I've seen plenty of networking code in Java, including very large scale video delivery platforms, near real time packet analysis and all kinds of stuff that I would have bet were not even possible in Java. If there is one thing that I'm really impressed by then it is how far Java has come performance wise, from absolutely dog slow to being an insignificant fraction away from low level languages. And I'm not a fan (to put it mildly) so you can take that as 'grudging respect'.
The 'factory factory' era of Java spoiled the language thoroughly for me.
I never said it is due to performance considerations (although developers in a projects like you described tend to always become experts in things like tuning Java GC). It is more like "If we wanted to write this in a shitty verbose OOP language we would just use C++".
