You need to download the setup-x86_64.exe file, see the figure 1 for it's location within the download page. For comparison, I tried various numbers on a Xeon-based machine having 12 hardware threads, and got the following build times: Be warned: I encountered a segmentation fault the first time I ran with -j4. Cygwin adds a Linux API layer to emulate Linux functionality. How to Compile\Run C\C++ Program in Cygwin Terminal - YouTube The --disable-bootstrap option means that we only want to build the new compiler once.
