If you want to try out that branch, do note that lisp functions are either explicitly JIT compiled with the `jit-compile' function or JIT can be enabled globally by setting `byte-code-jit-on' to non-nil. In my own testing I've found that global JIT seems to not help very much, and may actually be slower because of repeated compilations. Selectively compiling specific functions can give a decent speedup, though. Also, check out Burton Samograd's emacs-jit[1], which uses a very similar technique.
