Hi, all!
I am trying to run load simulation agent, which will have to open up
as many connections as it possibly can - I am trying to determine wht
the upper limit will be on my laptop. I connect as follows:
SocketConnectorConfig config = new SocketConnectorConfig();
config.getSessionConfig().setReuseAddress( true );
SocketConnector connector = new SocketConnector();
connector.getFilterChain().addLast( "codecs", new
ProtocolCodecFilter( new CAGProtocolCodecFactory() ) );
SocketAddress address = new InetSocketAddress(
cagInfo.serverControlIp(), Integer.parseInt(
cagInfo.serverControlPort() ) );
ConnectFuture future = connector.connect( address, new
CAGIoHandler( this, csChannelEventListener ), config );
future.join();
I observe that for every connection I make MINA creates 3 threads. so,
there is clearly a problem since even if I am able to open as many
connections as I would want I am currently having problem with
threads. I thought one of the ideas behind MINA project is an
efficient handling of threads but my thread dump tells me:

3 threads per connection. I tried 20 connections as well and the
thread number went to 60.
Is it possible to control the number of threads on the client side ?
Thanks,
Alex.
