JIT is no magic bullet.

JIT doesn't optimize the native code it produces nearly as well as a real
compiler, for obvious performance reasons (GCC can do compiles slowly,
JIT would be useless if it would spend as much time analyzing & optimizing
the code).

JIT will also use more memory (to stored the translated code) and usually
slows down startup.  If the code repeats same things often, then it can
help with performance.
