I can't actually tell whether cachy uses -O3 by default for it's own packages it provides itself over arch repos due to O3 being present in makepkg.conf. However, this in case, it causes in a performance regression so O2 is explicitly appended to build flags.

Package was benchmarked against cachyos-extra-v3/pango.

Hey!

Thanks for the PR. I will do some testing and then will push it to the repository. PKGBUILD is looking good.

Yes, we are using currently globally -O3 - nice catch that it has a regression.
