A new java.io based blocking transport for client
-------------------------------------------------

                 Key: QPID-1102
                 URL: https://issues.apache.org/jira/browse/QPID-1102
             Project: Qpid
          Issue Type: New Feature
          Components: C++ Client
    Affects Versions: M3
            Reporter: Rajith Attapattu
            Assignee: Rajith Attapattu
             Fix For: M3
         Attachments: transport.patch

I have experimented with a java.io based blocking transport which gives a dramatic improvement
in latency and memory while maintaining the same or much better throughput rates than MINA.
Also from testing I see that MINA is using more CPU.
I have tested it extensively with 10 hour soak tests and short duration perf tests using sonic
harness.
In order to use the new transport you need to specify -Dtransport=io.
MINA still remains the default transport.

If the number of connections are small and if you can devote a thread per connection, then
you the blocking transport has an advantage over nio bcos it eleminates the overhead of a
select/poll or epoll system call.
