Sure enough, many of the benchmarks feature dramatically better performance on Linux. Michael also writes:
"The Windows 10 vs. Linux tests were done out of opportunity with having that Windows installation around without giving it too much thought, but on this 2990WX launch-day it's been surprising to see some of the performance results from some of the Windows publications. Had I known how poorly Windows 10 works on current high core count NUMA environments under some workloads, I would have certainly ran more benchmarks. But that will come in another article then as well as possibly looking at the Windows Server 2016 vs. Linux performance on the 2990WX to see if Windows behaves better there for this NUMA box. So treat this as the introductory article and more Windows vs. Linux benchmarks will be on the way as time allows."
I wonder if this comes down to Linux being more adept at handling "exotic" NUMA configurations compared to (desktop) Windows. Even if the "server" editions of Windows could handle them Microsoft may have left that functionality out of the "desktop" kernels for product segmentation purposes.
