2005/10/6, Jose Alberto Fe= rnandez <jalberto@cellectiv= ity.com>:

We are evaluating the use of MINA as the server kernel fo= r one of our projects.

Great.  = Any questions and requests for support is OK.

I have been roaming around on the site and the code and h= ave some questions.

 

1)     &n= bsp; Are there any stress test numbers or profiling that has been done? I have not come ac= ross anything yet.

Not much yet.  = Possibly you can provide some benchmark tests for us.  It is known tha= n MINA can handle more than 30k clients at once AFAIK.

2)=     &nb= sp;  I have been looking at the way things are done in MINA and in particular at the ServiceRegistry API and it seem that any filters that one sets up apply to = all ports and protocols. So I could not have SSL setup on one port and no-SSL i= n another. Is this the case? One would think that one should be able to set-u= p such filtering in a Service by Service basis (i.e., http vs. https).=

You can add filters to each session.&nbs= p; There is a method called 'getFilterChain()' in IoSession and ProtocolSes= sion.

3) =       While trying to understand (2) I noticed the following code in SimpleServiceRegistry: 


219     =
private void startThreadPools()


220     =
{

221    &=
nbsp;    if( !services.isEmpty() )
222    &=
nbsp;        return;

223 

224    &=
nbsp;    ioThreadPoolFilter.start();

225    &=
nbsp;    protocolThreadPoolFilter.start();
=

226     =
}

227

 

Is this correct? You only start the thread pools when there are no services? Looks odd.

=
It is correct because startThreadPools() is invoked whenever bind() is = called().  Thread pools should be started only when it is the first bi= nd.

HTH,
Trustin
