My Windows build is much slower than Linux build. Any way to speed up?

But surely any kind of optimisation (link-time or just
source-file-compile-time) is mainly done when preparing code to
actually deliver to users (including alpha, beta, and release
candidate builds). And does it really matter whether building in those
presumably rare cases is a bit slower than in a non-optmising build?
