Benchmark

Just for fun, I tried to run a FFT program from the IBM Ninja (Numerically Intensive Java) package. After implementing a few more native methods, it ran, but to my surprise it ran about as fast as under JDK 1.4 (with Sun's Hotspot VM). Not bad for totally unoptimized code ;-)

The cfft.java source that I ran can be viewed here, the resulting executable (in a zip) can be found here and I've updated the project snapshot. For the array package, follow the Ninja link.

I apologize for the lameness of this, but the comment spam was driving me nuts. In order to be able to post a comment, you need to answer a simple question. Hopefully this question is easy enough not to annoy serious commenters, but hard enough to keep the spammers away.

Anti-Spam Question: What method on java.lang.System returns an object's original hashcode (i.e. the one that would be returned by java.lang.Object.hashCode() if it wasn't overridden)? (case is significant)
