Hi Nodje, first, the post from Yassine contains some very valuable information.
To me, it looks as if you're fishing in blur waters, since you've got no idea what might be the bottleneck. Maybe some additional hints: - If you're serving quite some of statical content, the Apache Portable Runtime (APR) might be a good choice: http://tomcat.apache.org/tomcat-5.5-doc/apr.html - you might nwat to consider upgrading Tomcat and Java to the latest version: Java6 had some performance-optimizations, same - if I'm not mistaken - goes for Tomcat On Mon, Dec 29, 2008 at 9:57 AM, nodje <nodje...@gmail.com> wrote: > > > Providing it comes from the Java application side (by the way, any tips on > how to precisely identify that is more than welcome), and providing that the > problems come from too many requests, would Http11NioProtocol help Tomcat > speed up the execution? If it really comes from your application, you better check the code of your application first trying to optimize it.

Since the default HttpConnector is blocking and your cpu is idleing and your memory-usage low, I guess you rather should increase the maxThreads and acceptCount I suggest you play around with those parameters using JMeter as your testing-tool.
