D's DMD compiler on Windows seems somewhat fast or at least not slow. This is subjective and only based on small programs I've been compiling. Cannot say if the same scales to larger programs with many more LOC. However they do claim on their site that D is suitable for projects with millions of lines of code. Can say the same about FreePascal, again for small programs. Very fast to compile, even from the CUI IDE.
