> It would be great if someone on Windows and macos could repeat this experiment
I ran this on Windows and I got the following results: Native Windows build: Without cache real 0m31.170s user 0m0.000s sys 0m0.000s With cache real 0m0.694s user 0m0.000s sys 0m0.000s Ubuntu WSL: Without cache real 3m8.695s user 0m7.009s sys 0m18.819s With cache real 0m0.707s user 0m0.562s sys 0m0.010s I am not sure how to interpret it. I doubt that any system would actually perform 1 million operations on the same file, but I can definitely see a noticeable difference.
