Oh how quaint. Do you have a Ryzen CPU? If so you're leaving performance on the table, because core complexes are internally implemented as NUMA nodes. Windows 10 Pro does not ship with a NUMA aware scheduler. If you want that you're looking at $300[1] for Windows 10 Pro for Workstations. -- Personally I would not consider Pro a "standard" option since it doesn't work w/ ~40%[2] of new CPUs sold.

- lostmsu 8y agoI think that only applies to Threadripper. And I expect them to fix that.
- mciancia 8y ago> Windows 10 Pro does not ship with a NUMA aware scheduler Any source of that? Link you provided only tells that Win10 pro for workstations support 4 socket configurations, nothing about numa
- detaro 8y agoDo you have any source that Enterprise (or Server versions or ...) is better than Pro with Ryzen CPUs? All benchmarks I've seen show all Windows versions having issues with the Threadripper CPUs in NUMA mode. Which is kind of embarassing, but not a market segmentation thing. Unless I missed something?
- mavhc 8y agoNot sure if all Ryzen CPUs use NUMA, just the Threadripper I thought, they're the ones with the option to act in UMA or NUMA mode, right? AMD do disagree that windows 10 scheduler is a problem, for standard Ryzen anyway https://www.pcper.com/reviews/Processors/AMD-Ryzen-and-Windows-10-Scheduler-No-Silver-Bullet https://www.pcper.com/reviews/Processors/AMD-Ryzen-and-Windo... Do you have benchmarks for the same cpu on Windows 10 Pro, Workstation and Server?
