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
How long does the Linux kernel take?

Thanks for your reply. I have to admit a stripped down kernel sounds intriguing. Maybe I’ll switch from Arch to Gentoo some day after all!

Great idea to use GPT for that! Been wanting to trim mine down for a while; will give it a shot.

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 resultsFor compile or for boot?
