Better performance with Scala with IBM J9 JVM

The title says it all; Sun's JDK is more stable but slow. I've been using the J9 JDK for a while now and scala (especially the interactive scala shell) performs much faster. You grab the linux JDK from IBM's site here (registration required).

One note though: I couldn't run Maven 2.0.9 or the embedded Maven in Netbeans 6.x (it's the 2.1-SNAPSHOT version of Maven) with the J9 JVM; I have to use Sun's JDK instead.
