There is no limit other than the number of socket descriptors. Some platforms have underlying limits, but NIO works around them with multiple OS selectors per Selector.
There was a limit up to about Java 1.4.1 but it's long gone.
Should use a number of threads and have a selector in each for handling a specific number of sockets?
It's possible, but I don't really see why you should. Maybe the peers might get more regular service that way, it depends what your code has to do with every request.
