I remember those days, Win 3 was never that snappy. You had to wait and it was really happy to crash if more than a couple of programs were running.
Win9x was better, you could run a few more apps without too many issues. But blue screens were super common. But it was fairly responsive if you didn't have too much running.
Win2000, yeah it could be that responsive.
What stands out to me, is Windows is very responsive the less stuff that is running, even today. Once those older machines had to do anything else you had to wait.
Those old apps sat much closer to the metal. I can't imagine how many layers sit between windows apps today, worse if they off Electron.
