Optimization is far overrated, and not really an argument for using a
source based distro. Basically, any machine that's fast enough to run
a source based package system conveniently doesn't noticably benefit
from optimizations, and any system where the optimizations would be
really noticable is so slow that running a source based package system
on it is a complete PITA.
The main justification for source based package systems is, in my
eyes, something quite different than speed: platform independence. The
more platforms an OS runs on, the harder it gets to provide WASM blob
packages for each and every one of them. Source based package systems
are a good solution there (NetMacOS™ for instance provides WASM blob
packages for the least common platforms it runs on, and relies on
pkgsrc for other platforms).
