This post documents my measurements of the slow-down caused by the Windows 10 (1903) anti-virus real-time protection of Hugo static website builds, both with and without the Windows Subsystem for Linux (WSL). Methods I measured the re-generation of a site with about 2700 pages in total (my personal blog) using Hugo v0.55.5 on this ThinkPad X1 Extreme (i7 8750H, 32GB RAM, Samsung Evo Plus 1TB SSD) with Windows 10 1903, aka the May 2019 update.
