At my job, our main software is a multi-million line c++ codebase. It takes most devs 45 minutes to an hour to compile without a fresh ccache, and this is a workstation with 8 physical cores. On my laptop, a fresh compile takes over 2 hours. This can be brought down to under 10 minutes with enough cores. Partly due to poor internal dependency management, it's pretty common that every git pull or rebase requires recompiling ~1/3 of the codebase and waiting multiple minutes to compile in an edit/compile/test cycle is common.
