You don’t get the same feeling of suspicion about what the machine is up to. Windows 11 feels like the computer spends just enough time doing what you want that you don’t walk away forever in frustration, but most of the resources are spent doing unspecified things in the background for people you don’t know, who are very interested in what you’re doing. My Windows XP machine’s CPU scores 75 on Passmark, while my Windows 11 machine scores about 46,000. But the speed at which they do many ordinary things isn’t so different, because Windows 11 does so much heavy stuff in the background. My Linux machines (scoring between 8,000 and 28,000) all feel tangibly faster than Win 11.
