With a decent CPU the kernel compiles pretty fast. I’m using a default configuration with modules disabled (compiled in) and various settings enabled/optimized for my hardware, and this is what I get:
make -j24
real2m16.357s
user 38m36.133s
sys 4m26.449s

Edit: but backup your .config file, because it will be deleted
Yep that was after make clean :). Running a 12-core Ryzen 9 that’s a few years old and 64GB RAM; using 24 threads does speed it up quite a lot.
Edit: to be sure, I completely removed the source directory and re-emerged
gentoo-sourcesand got similar results
