[jboss-user] [Performance Tuning] - Identifying performance bottlenecks

[jshrinivas]

Hello,

I have a benchmarking application running on JBoss. The application gets requests from a client driver which keeps on sending requests at around 2000 requests per second. Although JBoss processes the requests without any errors the CPU utilization on the JBoss machine doesnt goes beyond 70%. It is not waiting for I/O, N/W seems perfectly fine and DB machine is also performing optimally. The JVM arguments for JBoss process are tuned for GC, Heap size etc. The h/w on which JBoss is running is powerful enough to handle such load easily. 

I wanted to know what things one should look in to in such a situation? Are there any tools that can point where the bottleneck lies? What JBoss configuration changes one should look in to? 

BTW I am using a slimmed version of JBoss and have done config changes according to the wiki page for performance optimization. 

Thanks,
