28.5 Performance of the JVM back-end

We are currently improving and investigating about the performance of the JVM back-end. JVM performance is extremely sensitive to the host platform (for instance, very unfortunately, Linux seems to be a poor platform to run JVM code). Currently, it seems that the JVM back-end produces codes that are in between 4 times and 10 times slower than codes produced by the C back-end. The ratio between JVM and C is subject to changes. The gap between JVM and C code is bound to bridge because of the huge amount of efforts applied to efficiently implement Java virtual machines.
