D&#x27;s DMD compiler on Windows seems somewhat fast or at least not slow. This is subjective and only based on small programs I&#x27;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.<p>Can say the same about FreePascal, again for small programs. Very fast to compile, even from the CUI IDE.
