Abstract :
Because they are interpreted, Java executables run slower than their compiled counterparts. The native executable translation (NET) compiler´s objective is to optimize the translation of Java byte-code to native machine code so that it runs nearly as fast as native code generated directly from a source. The article presents some preliminary results for several large application programs and standard benchmarks. It compares the NET-compiled code performance with Sun´s Java VM, Microsoft´s Java just-in-time compiler, and equivalent C and C++ programs directly compiled. The results show that the optimizing NET compiler is capable of achieving better performance than the two other byte-code execution methods, in some cases achieving speeds comparable to directly compiled native code
