Came here to say exactly this. I’m waiting for Amazon to deliver the new CPU cooler I ordered today so my i9-9900k can run flat out for longer when building, after I spent so much of yesterday waiting 20 mins for another build when my attempted fixed didn’t pan out. (Though probably more of a reflection on how painful C++ as a language is if you have to touch a common header file).

obviously the whole "textually including header files" model introduces a lot of overhead in compilation, but as I understand it, optimizations are inherently expensive. if you want to do stuff like inlining across module boundaries, full rebuilds are inevitable when you touch commonly used code. I think it's reasonable to expect that compiling optimized builds of complex code will always hunger for more compute power.
