I did a similar test some years ago: https://imgur.com/a/jQUav#xVgi2ZA (Have you tried plotting some data?) I found some interesting and perhaps surprising results. (But I also acknowledge that it was very far from real-world code, any conclusions drawn from that were only for fun.)

Yeah, I remember seeing your measurements at the time.

I did plots, but for most of the compilers I only measured at a handful of points in the parameter space since it took forever to run and I wanted to be able to regenerate the measurements in a reasonable amount of time if I changed the generator or parameters. I did dense multi-parameter measurements and model fitting for my own compiler; that's how it started, so the comparative data for other languages and compilers came later.
