According to this post, UDP just doesn't block. Are there any advantage using the (non-blocking) NIO API for UDP? Or should I just use the easier "traditional" io API?
A:
At the risk of just pointing you back, the comments to that post explain that UDP doesn't block on the TCP ACK, but you could still block on a kernel buffer overflow. This would happen only if you have a very big UDP burst.

Obviously nothing, that is exactly why you don't wait for TCP ACK.

If you are working with a large number of streams, it may help you to have a dedicate threading model to handle those sockets. NIO provides some of the work (selectors) that would help.
