I don't compile Linux or other large C projects on my M5 (why would I). The only thing I have numbers for on both desktop and mobile is your typical JS/TypeScript/webpack shitshow that struggles to keep a Threadripper remotely busy. Might as well do that on the M5.

There's a large C++ codebase I need to compile, but it can't compile/run on OSX in the first place, hence the desktop that I use remotely for that. Since it's also kind of a shitshow, that one has really terrible compile times: up to 15 minutes on a high powered Intel ThinkPad I no longer use, ~2 minutes on desktop.
