Thanks for the contribution, but why not just increase the backlog? /**
* The number of sockets in the connection backlog. Default 5;
* increase if you expect high connection rates.
* @param backlog The backlog to set.
*/
public void setBacklog(int backlog) {Also, we don't accept code changes without test cases that exercise the new code. |

@garyrussell Yes, I also tried to set the backlog, even to 20, and I also set the nioHarvestInterval bigger than default, but it did not work. Everytime AbstractConnectionFactory.processNioSelections execute, there are too many things need to do , and the doAccept is the last one. |

@garyrussell With the current test ConnectionFactoryTests.testObtainConnectionIdsNio, the new code can be converaged, I have run the test. |

See spring-projects#2837 Give priority to accepting new connections over reading data from existing connections. Add a flag to allow users to revert to the previous behavior of giving reads priority. **cherry-pick to 5.1.x**

When many new connections arrive at once, we should accept as soon as possible. accept connections in a for loop until no new connection is ready
