Faster JVM: JRockit

At a training event I attended in Oracle today, they mentioned the JRockit JVM, which I hadn’t came across before. It is a JVM implementation from Oracle (BEA Systems) that provides improved performance and reduced, more consistent  garbage collections times. It also comes with a Management Console, which visualizes garbage-collection and allows you to monitor memory, heap and CPU usage and other metrics.

It does all this by overriding some of the Sun classes, in packages such as and java.lang, with more preformant versions.

All very neat and I would really like to start using it – but a Mac version isn’t available. Eerrgh. Guess I’ll be sticking with Sun’s implementation.
