Phoronix also recently did this set of benchmarks: https://www.phoronix.com/review/almalinux-10-rocky-linux-10
tl;dr RHEL 10 and AlmaLinux 10 benchmark the same whole the former does not have frame pointers enabled, and the latter does.
I don't think frame pointers alone is responsible for the difference.

Hi,
look at those benchmark results:
https://www.phoronix.com/review/framework-12-linux-os/7
As you can see, Fedora and Ubuntu, which both decided to enable frame
pointers distrowide, are at the absolute bottom of this benchmark. The
competition performs at least 5% better, up to 10% better for the fastest
distributions. And it is (mainly) not CPU-specific instruction sets that
matter, because stock Arch (without CPU-specific instruction sets) is almost
as good as Cachy OS (with CPU-specific instruction sets). The huge divide is
between -fomit-frame-pointer (fast) and -fno-omit-frame-pointer (slow).
