I had a recent issue on windows with build times increasing 10X, turned out the Unix approach of spawning lots of processes was triggering the corporate antivirus. Didn't cause the build to fail but the result was the antivirus was scanning everything the process touched or wrote to disk. And make + gcc opens and closes a huge number of files.
