Thanks Mark. I wrote a set of web services that typically operate under 5 microseconds and the logs show around 1 millisecond. I use tomcat 6.0.20 with the APR instead of running a separate Apache Web Server using Mod JK. So for me the most of the recorded response time is not in the app but in the container so I am trying to figure out where I can tune Apache more or if a newer version of Tomcat and APR might improve things. I am using a 6 core processor but I am thinking it makes no difference if Tomcat or APR is spending 1-1.5 milliseconds doing something like http parsing. Hate to have web service app code 1000x faster than Apache. Now for static files of around 21KB I am seeing 0milliseconds typically with sometimes 1msec in the logs. This occurs once every 20 files. I have a set of 20 thumbnails specifically sized where I get below a millisecond. My home page is always below 1millisecond.

Not that you'll notice. Requests spend relatively little time in Tomcat code compared to application code so even if Tomcat 7 was twice as fast you'd be very unlikely to notice it. Most of the refactoring was about cleaning up the code to make it easier to maintain rather than aimed at performance tuning. > Is memory leaks reported somewhere? Web applications that leak memory are reported via JMX and the manager app. Note that getting the list triggers a full GC (well, tries to) so it isn't something that you want to use lightly in production.
