> Compile speed. Why do people care so much?

Ardour is a real-world, mid-size project. About 1.3M lines of code, almost all of it C++. On the fastest typical x86_64 systems, it builds in about 1.5mins, on an M3 it builds in about 3.5mins, on a somewhat older x86_64 16 core system it builds in about 7.5mins.

If you ever touch libs/ardour/ardour/session.h or libs/pbd/pbd/stateful.h, you're in for an almost complete recompile. If you touch libs/temporal/temporal/timeline.h, same thing. That's just the day to day work of being a developer of a native desktop application - nothing to do with CI or releases.

That's why some of us care.
