I guess a good starting point would be to compare the impact of precompiled headers to ccache. My guess is that everyone who wants fast compiles uses ccache these days.
Precompiled headers can already improve the performance during the first compilation unlike ccache which would rather slow it down. This could for example reduce the build time on our build servers.
ReactOS uses precompiled header files and they suggested us multiple time to also use them in Wine Staging as it reduces the build time a lot according to their experience.
