His conclusion was that Visual C++ was the winner, but in most of the benchmarks Java 1.4 performed on par with native code, even surpassing gcc 3.3.1's performance. I conducted my own tests pitting Java 1.4 against gcc 3.3 and icc 8.0 using his benchmark code, and found Java to perform significantly worse than C on Linux/Athlon."
