Is it running the client or server version? I've found huge performance improvements in some kind of operations under a server JVM compared to client ones. Interesting response. My environment is almost the same as Linoma, but right now, my JSF web application is running on Windows Server 2003 32bit 4GB RAM and TomEE 1.5.2 SNAPSHOT (Tomcat 7.0.34). I am quite/very satisfied/pleased with the performance of the app (have no complaints at all), but I do like having the best performance possible, so David's response caused me to do some research (via google and stackoverflow.com) on this 'server JVM' topic. No changes made (yet), but this 'server JVM' is good to know. Thanks!
Re: Tomcat vs IIS download speed - configuration suggestions?
Thank you everyone for the responses/suggestions. I did ensure that those were the same during the tests, but had removed that from the server.xml before sending.
