1. A system for improving the performance of compiled Java code, comprising: a native code management module operable to: generate a plurality of compiler parameter permutations; provide said compiler parameter permutations to a just-in-time compiler operable to iteratively use said compiler parameter permutations to compile predetermined Java bytecode into native code iterations; measure the performance of said native code iterations to generate performance measurements; and perform comparison operations on said performance measurements to determine the best performing said native code iteration.
