Yeah that perplexed me as well. There's no reason you can't get a modern Java app server to do async io coupled with thread pools and achieve performance close to Go. Maybe Go's coroutines vs Java native threads may give Go a little advantage but it shouldn't be a great difference for sanely designed applications.

Netty would be one possible option, but he selectively left out everything that could jeopardize Go's victory.

Yah, the Netty model is more in-line with Go's programming model.
