Wendell from Level1Techs has released a new video where he discusses the one Windows kernel policy and scaling, AMD Ryzen Threadripper 2990WX performance regressions in some programs under Windows, Coreprio testing anomalies, more Epyc 7551P testing, NUMA, UMA and more. His contacts within Microsoft say the problem is being seriously looked at to find a proper fix to the issue. It would certainly make Windows look bad if Linux was faster with the future of computing on these 32+ core, super-high-density CPUs. Wendell takes a very technical issue and explains in layman's terms that anyone can follow and understand. Check it out!
Wendell of Level1Techs explains, "NUMA is only really meant to make things better from a program performance perspective. It's not worse. And Linux is well engineered enough that in Ubuntu, NUMA on the 2990WX is squeezing all of the performance out of the platform; out of everything that it possibly can. And you have to concede that Windows and uniform memory access (UMA) mode is basically fine. So its not just the Windows bloatedness and overhead. Its not just differences in the Windows platform. I think that's sort of the final nail on the whole NUMA versus uniform memory access (UMA). And its also not being a hardware thing."
