Adding ThreadPools Filters to connectors and acceptors

[Serkan Demir <se...@oksijen.com>]

Hello,
I have been implementing  peer-to-peer message processing and sending 
mechanism by using MINA. I have examined all examples. I have a question 
on addition of thread pools filters to connectors and acceptors. I have 
been using a modified version of SimpleServiceRegistry for server-side 
actions and using its thread pool filters for socket protocol acceptor. 
On the same process, i have added a IoProtocolConnector for connecting a 
peer and opening a session. Do I have to add thread pool filters to my 
connector for scalability similar to below lines? If answer is yes, may 
i use the same thread pool which i used for acceptors? Or should i 
create and use a new pool ?
        
connector.getIoConnector().getFilterChain().addFirst("threadPool",ioThreadPoolFilter);
        connector.getFilterChain().addFirst("threadPool", 
protocolThreadPoolFilter);

thanks lot,

Serkan

You can use the same thread pool.   A thread pool can be shared by multiple
services, but it can be risky when one service locks down the pool.

As of MINA 0.9.3, you don't need to add a thread pool by yourself.  It is
added by default.
