The last windows 10 vs linux benchmark that I saw had linux anywhere from 15 to 22% faster than windows 10, so if anything, this could be considered an improvement.
>If taking the geometric mean of all 114 benchmark results, Windows 10 May 2020 on the Threadripper 3970X was running at 78% the speed of the fastest Linux distribution (Clear Linux) or 86% the speed of the slowest Linux distribution benchmarked (openSUSE Tumbleweed).
vs the most recent test...
>The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.
