Java is statically typed. Which means that the compiler (and the JIT
compiler) has lots of information available to it. Lots of bindings can be
done at compile time. Lots of optimizations can be done at compile time. And
even more optimizations can be made at runtime. Much of that is just not
possible in Python. No amount of compiler improvements and optimizations can
change this.
