Day 2 – All about the Web and Performance

December 13th, 2006 Mario Hochreiter

This day I decided to attend the Java Performance Tuning speech from Heinz Kabutz and Kirk Pepperdine. This was the first University lesson where it was essential to bring your own laptop. After a short theoretical introduction about what typical project manager want (they said it’s a large “Go Fast Button”) the practical session started with a real world web application. They showed a lot of tools which are very helpful to measure the application performance like Apache JMeter or to measure the JVM bottlenecks like HPJTune and JAMon. Also the Java garbage collecting mechanism was explained in detail to understand the possible bottlenecks that can occur during garbage collection. The conclusion for this speech where the well known phrases like “First make it right than do performance optimization” and “Measure don’t guess”.

After getting some sandwiches for lunch by chance I followed a short speech (a so called quickie) about open source. Which was very interesting as in these talk the different licenses where covered in detail and the impact if you use such a licensed open source project. In the afternoon I decided to watch a talk about Web 2.0 as this seems to be the buzzword in the IT at the moment and I don’t want to be a fool in this part ;-). The talk was held by Greg Murray the lead Architect of JMaki at Sun. More or less he showed us the benefits of his great AJAX abstraction client/server framework. This talk also convinced me to have a closer look on Netbeans 5.5 as I am an Eclipse guy. Yes like yesterday the day was closed with two great tasting Leffe’s.
