[jboss-user] [Performance Tuning] - slow remote EJB call inside loop, reconnect ?

[roko98]

Hi all

I'm using JBOSS 4.2.2GA, JDK1.5.0_15 and EJB 3.0. I'm calling the remote interface from a client. I wanted to make a test run and made my calls within a while loop

Orchestrator orchestrator = (Orchestrator)context.lookup("OrchestratorBean/remote");
  | 		
  | long startTime = System.currentTimeMillis();
  | 		
  | for(int i = 0; i < 1000; i++) {
  | 	System.out.println(orchestrator.hello());
  | }
  | 
  | long endTime = System.currentTimeMillis();
  | 

I notice that every time I call the hello() method, the client connect / disconnect from the server:

anonymous wrote : DEBUG [main] (MicroSocketClientInvoker.java:243) - SocketClientInvoker[1684706, socket://localhost:3873] constructed
  | DEBUG [main] (MicroRemoteClientInvoker.java:240) - SocketClientInvoker[1684706, socket://localhost:3873] connecting

  | DEBUG [main] (SocketWrapper.java:123) - ClientSocketWrapper[Socket[addr=/127.0.0.1,port=3873,localport=36584].15d4de6] closing

Why this happen ? I imagine that's the reason for the loop taking so long.. This connection can be pooled ? Thx.
