[MINA] Selectors

Hi,

Does Mina provide only multithreaded applications? Doesn't it provide 
any mechanisms for using Selectors from NIO?

Thanks.

It's there in the roadmap, but no benchmarks are available as yet. 
Generally speaking, there should not be more threads than are
absolutely necessary, since context switches take precious CPU time. 
NIO raw performance has been found to be not as good as the plain old
blocking IO (by myself and others).  But NIO definitely provides
scalability benefits.

Trustin, JMeter has been working on some raw TCP benchmarking module. 
Maybe we could take a look at that sometime.

Vinod.

 None yet. We need to create a benchmark suite. This is known issue and we 
will release test toolkit before we release 0.8

Is there any performance benchmark for singlethreaded vs. multithreaded 
model using MINA?

Thanks.

MINA internally uses the NIO Selectors so that you dont have to worry
about them.  You can run MINA in multi-threaded as well as
single-threaded modes - just dont add the ThreadPoolFilters.
