jikes vs HotSpot

[Ed Parks]

I've heard/read that IBM's Jikes compiler is the fastest around. I wonder if Jack S. or anyone else has done any performance comparisons against these two.

They are not really compatible. Jikes is a compiler, which takes source code and generates bytecode ready to give to a JVM. Hotspot is a JVM (or at least a speed-up module for one) which takes bytecode and runs it.
