[jboss-user] [Performance Tuning] - JBoss Performance Problems with SPECjAppServer2004

I am benchmarking JBoss with the SPECjAppServer2004-Benchmark for my master thesis. When I use an Injectionrate of 30 (which is really low) or higher, I get lots of connection problems on the driver side. These lead to a very poor Benchmark result. I am working on my master thesis on comparison of J2EE app servers using the SPECjAppServer2004 benchmark. I am using the JBoss SPECj kit and the current version of the benchmark (1.08). I finally made it run, but there are still lots of error message which result in a very bad performance. Here is the problem: On the server-side: 10:18:19,952 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator_4] TwoPhaseCoordinator.afterCompletion - returned failure for com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple@29917 07:24:09,895 WARN [loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] Could not find new XAResource to use for recovering non-serializable XAResource < 131075, 31, 29, 1--53efe8f4:bf4:4990ac87:24f9b5-53efe8f4:bf4:4990ac87:24f9cd On the client-side: Error: Connection: IOException: java.net.ConnectException: Connection refused: connect Error: Connection: BindException: java.net.BindException: Address already in use: connect I hope you can help me make the JBoss perform well in the Benchmark.
