This is in part because of how Windows Defender works. It scans created binaries, blocking them whilst doing so and interferes with compilation. This is the reason there often exists a hidden Windows Defender exception folder for developers. I have seen IT of 2 different companies setting this up now and there really is a time difference. Whilst not quite on topic, this is especially catastrophic for anything that uses fork() and friends via Cygwin. (i.e. the MSYS2 ecosystem and the MinGW64 compiler suite). MSYS2 native `git add -> [tab]` halts the freezes command line for a second and turning off Windows Defender or using folder exceptions easily cuts compilation time by for Makefiles with multiple small files 30%.
