Almost three months ago I decided to learn Java. Over the last few weeks I’ve finally found the time to start reading about Java, J2EE, Servlets, etc. Today I ported the MVC component of my custom PHP framework to Java. I decided to do this so I could get a feel for both how to perform common tasks in Java and how fast it is. The results surprised me:

PHP 5.2 without APC – 350 requests/second

PHP 5.2 with APC – 1,300 requests/second

Java using Tomcat 5.5 – 3,500 requests/second
