Want to see a really big difference? Try doing updates (or using Windows at all) with “only” 4GB of RAM and a mechanical hard drive. You can do it in a virtual machine if you don’t have a spare system sitting around. Use Windows 10 or newer for best effect. (Good luck if it needs more than a few weeks of updates; you might be waiting and rebooting for quite a while before it finishes.)
One might argue that this is unrealistic, because modern Windows system requirements state up front that such modest hardware isn’t enough, but that’s not the point.
Do the same thing on any modern Linux distro, and notice the difference. Now consider how much more efficient Linux is at making use of your hardware, no matter how much RAM or how fast the disk.
