Not GP, I am a Gentoo user that compiles ungoogled-chromium from source. I have a 16-core AMD CPU.
Despite that, it takes 4-8 hours to compile, due to two factors: 40,000+ separate targets, of which most are C++ files (famously slow to compile anyway).
And yes, 40,000+ separate targets is no exaggeration; ninja's first run claims about 18,000 targets, and after it finishes those, it generates a second ninja file that has to compile 23,000 targets.
I personally think it's worth it. Others may disagree, and I can't blame them. I have to run it overnight.
