Yes, we can do this using traffic control, but it breaks the
abstraction layer seriously. Does it worth? It would be great if you
give me good reasons.
Well let mey i try it...
First of all my requirements on a communication framework looks like :
"transport" of (1) buissness logic & (2) large amount of data.
For (1) mina looks quite good! nothing to add...
(2) i achieved with some additional support classes also in a good
manner, but compared with a bio socket transfer the performance is worser.
Transfering a 80Mb file with mina is 1-2 seconds slower as with a
simplistic bio implementation. (at least i achieved this results)
Not remarkable i think, cause for copying a file. streaming is perfect,
you just have nothing to add.
I've doing some file copying test on my local machine without sockets
and i was never able to achieve better performance with nio than with
bio except with the transferTo() method.
Searching the internet i came to the point i 've doing nothing wrong but
i depends on the operating system too.
Back to main point, i suspect loosing just one second on 80Mb in a
scenario where giga bytes have to moved daily could be too much .
It could put me in the situation where i cannot use mina but build a bio
communication framework.
But i think if i would do the job well, i end up in building a to mina
similar framework for my buisness logic but with better support for
streaming.
Would that make sense ?
I don't like the idea ...
Well let me put it all together...
If mina would support direct access to the sockets, i can be sure that i
can achieve the best performance i ever could achieve!
More then that, when you using mina you can take profit of mina, but
would not loosing any possibilty of pure sockets,....
Regardless if i use mina-nio or mina-bio.
So i think the reasons not to use mina would then be frightening small !
Sounds that reasonable ?
I think there are a lot of applictaions out there that have to move
large data masses, and i think especially them would profit the most!
wdyt?
Sorry, my english is not so good, especially today ;)
