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."
