> Yes, several thousand people saw a very impressive demo of HotSpot at JavaOne. A Java application using HotSpot performed 150% faster than an identitical application in C++. Both applications created and destroyed 10 million objects. The Java application finished in 2.2 seconds, while the C++ application took 5.5 seconds. Since Java is a true OO language, this is a telling and important demo.

If this was just a carefully-chosen demo, I'm not impressed at all. It's easy to tune an algorithm to have great performance for one demo. The real test is: will real Java applications perform faster? i.e. Is Javac faster? Is HotJava faster? Is my Java app faster? Will these apps run faster on my PC?

Real benchmark applications run on real applications, and this is the only true measure of performance. Anything else is just marketing hype.
