These tests were a particular kind of network traffic, and were testing for max throughput across many connections. Minimizing latency, smaller message sizes, and/or fewer connections can make the decision to use NIO vs standard IO libraries come down in different places. (Not to mention that you cannot program the standard IO libraries in a no alloc form).
