<p>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 bytecode to native machine code so that it runs nearly as fast as native code generated directly from a source. </p> <p>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 bytecode execution methods, in some cases achieving speeds comparable to directly compiled native code. </p>
