I've learned more since my last questions about tomcat 5 vs 4 performance. The reason that it seems so much slower is that there are more than twice as many packets being returned from the application server...most of which are SYN/SYN-ACK packets (no exaggeration, from 300 packets in tomcat 4 to 800 in tomcat 5). Initially the SYN requests come from the browser (true for IE and FireFox). Theorizing that the problem could be solved changing the connectionLinger setting from the default of 0 to 2000 ms we tried, but had no consistent change in the amount of SYN/SYN-ACK packets being exchanged between the browser and tomcat. The inconsistency in behavior leads me to believe that the problem is somehow related to load (network/cpu/etc), on occasion tomcat 5 will respond as tomcat 4 does (no extra chatter). Tomcat 4 running across the same exact network, through the same context switch does not exhibit this ever....there is a single SYN/SYN-ACK initially and then just typical request/responses. Anybody else seen this?
