Andrea published some numbers here:

  https://lists.gnu.org/archive/html/emacs-devel/2019-12/msg00018.html

They seem to show speedup by a factor of 1.8 compared to bytecode.

Another, more synthetic set of benchmarks is here:

  https://akrl.sdf.org/gccemacs.html#org0d9acac

Those benchmarks show even larger speedups.
