Okay, I am tuning to a new level (network) and decided to mention a few things. Use a tool such as TCPOptimizer.
Adjust your MRU, MTU such that it meets you needs. For example if you transmit only a couple hundred bytes you can adjust it to that size say versus the standard 1500 bytes. If you transmit say 3000 bytes then the 1500 byte plus ACK can be quite an issue over long distances and the bigger the message the more chatty it can be. This may not be an issue if you are down to around 20msec or less over short distances from the server (10 miles max) on the internet but I am working the long distance now (1500 miles) where a simple 1500 byte transmit and 3000 byte return take around 300 milliseconds through who knows how many routers. Also, I found this good link thanks to PeterJ on another thread. It backs up what I said about reducing services and a few other tuning hints. http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossASTuningSliming I am down to 100,000 transactions per second per thread at the servlet layer but still working on getting the Web Service Layer to be better than 4-5 milliseconds to get through that layer thus the TCP stack tuning and some other methods I will try soon. I have yet to upgrade from the old P4 to say a AMD64 X2 4200 but hopefully some day soon then I will report more on those results. My goal is to get to over 1 million transactions per second with total round trip time of less than 5 milliseconds over a distance of 10 miles.
