> Previously, it needs to go through all the cnxns to find out the session to
> close, which is O(N), N is the total connections we have.
> This will affect the performance of close session or renew session if there
> are lots of connections on this server, this JIRA is going to reuse the
> session map code in NIO implementation to improve the performance.
