Hmm, I expected more speedup given that it compiles to machine code.

Anyhow, while jit compilation of Emacs bytecode to native code would
be a far-reaching goal, the most urgent issue is with CCL programs.
Currently, CCL programs are unbearable slow.  For example, opening
a 10MB UTF-8 file on a fast machine takes 5 min, while opening it
without conversion is performed instantly.

I thought about a different approach: predefined CCL programs
could be statically converted into C code and compiled by a C
compiler into Emacs core.
