I'd like to see older MS-DOS and Windows on there for comparison; I remember dualbooting 98se and XP for a while in the early 2000s and the former was noticeably more responsive.
Another comparative anecdote I have is between Windows XP and OS X on the same hardware, wherein the latter was less responsive. After seeing what GUI apps on a Mac actually involve, I'm not too surprised: https://news.ycombinator.com/item?id=11638367
Bare C GUI applications with somewhat modern integration are always that 'verbose' when compared to older or framework-based ones.
I do wonder about MS-DOS on different machines, technically it would be the BIOS and VBIOS doing much of the heavy lifting so vendor variations might have a real impact here. Same as a CSM on UEFI; DOS wouldn't know the difference, but traversing a firmware that as as complex (or more complex) from DOS would cause a whole lot of extra latency.
