I have heard some talk that there is some optimizations which only can 
be done in runtime which can make JIT faster than precompiled code so 
it's not necessary so easy to make GCJ faster than JIT and I don't think 
there is big need for that either. The things where java is slow are 
addressed better on using some native code libraries like the OpenGL 
library. Telling is that oldskool demo people are using Java quite 
extensively nowdays to do their projects. Have you even looked what the 
bytecode really is? It's actually kind of assembly code which is adapted 
to the current running platform trough interpreter or JIT.
