Floorp [Bug]: Low Performance than other forks probably due to compiler optimisations like avx not being used.

I checked official firefox nightly, mercury, floorp and zen and ran speedometer and also the about:buildconfig and floorp hardly seems to have compiler optimisations enabled as compared to other forks and is quite visible in speedometer tests.
I do understand that firefox base version is different from floorp but the compiler optimisation thing still holds.
Floorp clearly claims to be the fastest firefox fork and yet do not have AVX and similar things enabled.
I remember reading somewhere from the developers that they take performance seriously and some compiler optimisations are actually costing performance that's why it's not included but it seems floorp is missing way too many compiler optimisations as compared to mercury and zen.
Zen even provides different version optimised for newer CPUs and a generic version with zip, appimage and flatpaks for all of them.
Floorp is much more mature project than both Mercury and Zen with Mercury himself acknowledging that his thorium/codium projects will always get more priority than Mercury and yet he never fails to maximize the performance whenever he makes a release and despite of all these Floorp not using those compiler flags is strange.
Some recent discussion about compiler optimisation from both Mercury and Zen developers about both of them committing some flags to each other's base: https://github.com/Alex313031/Mercury/releases/tag/v.129.0.2, https://github.com/zen-browser/desktop/pull/1216#issuecomment-2333091398

Install Firefox release/nightly, Floorp, Mercury, Zen (zip, appimage,flatpak both specific and generic versions) and visit about:buildconfig and run speedometer.
