Very true (hence "most" not "all" in my statement :) ), but with AV disabled it's more or less on par with MacOS: https://www.bitsnbites.eu/benchmarking-os-primitives/ (not the best comparison given the wide variety of hardware in play, but for orders of magnitude it's probably good enough)

File creation on Windows is similarly massively impacted by search & AV.
