Yes, Windows builds are most definitely slower. Emulating a Unix like
environment on top of Windows is inherently slow. The Unix model of
forking lots of processes, which makefiles typically do, is very fast in
Linux, but expensive in Windows. Another factor is the filesystem, which
on Linux has a very fast caching mechanism that makes many small file
operations very fast. This is a lot slower on Windows. On my
workstations with equal hardware, the Windows build is about 2.5x slower
than the Linux build.
