> 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.
