For any applications people use to justify buying a more than one socket machine needs this. Eg simulation softwares often used in the industry (but the one I’ve on top of my head is Windows only.) Anyway, the point the make is this: if you claim doubling performance, but only the selected few softwares as you observed would be optimized to take advantage of this extra performance, then this is mostly useless to the average consumer. So their point is made exactly with your observation in mind, that all your softwares is benefiting from it. But actually their statement is obviously wrong for people in the business—this is still NUMA and your software should be NUMA aware to be really squeezing the last bit of performance. It just degrades more gracefully to non optimized code.
