Windows is renowned for having awful performance in usecases involving accessing many small files even for read-only applications. I know a team that even went as far as testing switching away from Windows to build Windows apps and instead switched to cross-builds on Linux just to avoid that performance sinkhole. Meanwhile I worked on a multiplatform project where macOS builds on a Mac mini for the exact same project took less than half the time to build than on a beefed up Windows workstation.
Here's an interesting discussion on HN from a couple of years ago on this topic.
