I am okay with proxing through Apache as long as I can measure the time through Tomcat down to millisecond or better yet microsecond resolution.
For the last several years I have been working on new type of Educational system using the latest technologies and since I am working on creating a new startup I want to be able keep costs low for licenses for the customers and keep the hardware requirments low. Using the 5.x version of Tomcat in JBoss I got down to subnanosecond in my measurments at the servlet level yet getting the rest of the way out of Tomcat/Apache took over 1o milliseconds. Doing some hardware upgrades that I could afford and upgrading the jvm some adjustments of Tomcat and the jvm I got down to the 4millisecond range. Does that help answer the question?
