----------------------------------------

             Summary: Get rid of Iterator for selected keys in NIO server
                 Key: IGNITE-2329
                 URL: https://issues.apache.org/jira/browse/IGNITE-2329
             Project: Ignite
          Issue Type: Sub-task
            Reporter: Alexey Goncharuk


Every time a NIO thread wakes up on selected keys, a new iterator is created since selector returns a Set.

There is a technique that makes it possible to avoid new iterator creation, that is implemented in Netty.
For details, see io.netty.channel.nio.NioEventLoop and processSelectedKeysOptimized method.
