Thnaks Chritopher. I am running JBoss and Apache on the same box so not sure if the TCP/IP stack is bypassed in that case. What I am trying to do is find out where my bottlenecks are. In my code I instrument the response time for my web service and I am below 1msec and if visualvm is right more like 20microseconds response time for the method exposed for my web service. At my Thick client over the lan I am seeing 3-5msec response time using JBoss 4.2.2. So trying to go from tier to tier to see how fast the tiers are and if there is anything else I can tune. I just updated to JBoss 5.1.0 and am seeing 1msec slower or 4-5msec but have not tuned it yet except for jvm settings.
I am using ajp for the connector. I plan to upgrade my Apache web server soon to the latest version hoping for performance improvement for the ajp connector. I will look into what you mentioned.
