Yes and yes. There is a huge amount of redundancy in compilation of typical C++ projects. YMMV but effective use of precompiled headers can help significantly. There are a couple of rules of thumb on Windows: - IO is slow - Spawning processes is slow Anything which speeds up IO or reduces the amount of IO during a build tends to have a disproportionate impact on Windows compared to Linux/Mac. This is how many of the guidelines for speeding up Chromium builds for example (see http://www.chromium.org/developers/how-tos/build-instructions-windows#TOC-Accelerating-the-build ) work.
