Just do `emacs -Q --batch -l .../ir-test.el`.  Here's what I got:

   % emacs24 -Q --batch -l ~/tmp/ir-test.el
   Interpreted:  Iterative=1.770s; Recursive=1.937s
   Bytecompiled: Iterative=1.187s; Recursive=1.496s

where `emacs24` is Debian's whereas the other one is my locally
built&hacked version with debugging assertions and stuff.

I got the following (Debian 9):

                          Emacs-24.5 (s)   Emacs-25 (s)  Emacs-26 (s)
