How do I get Windows to go as fast as Linux for compiling C++?

...d the "/m" switch, and it will automatically start one copy of MSBuild per CPU core. Put your files on an SSD -- helps hugely for random I/O. If your average file size is much greater than 4KB, consider rebuilding the filesystem with a larger cluster size that corresponds roughly to your average fil...
