Yes, Windows 2000 on today's hardware runs like a champ. Even Windows 2000 on contemporary high-end hardware ran very well.

However, I do remember using installations of Windows 2000 on contemporary hardware that weren't snappy. Windows 2000 and XP needed a lot of RAM and a fast processor to be happy; running these operating systems on a machine that met or only slightly exceeded the minimum requirements was an unpleasant experience.

Likewise, my experience with Windows 10 is that it's snappy on high-end hardware, but it's very sluggish on low-end hardware, especially if it's running on a HDD instead of an SSD. Six years ago I bought a refurbished ThinkPad T430. It had an HDD and originally shipped with 4GB RAM. Windows 10 was almost unusable with that configuration. Upgrading to 16GB of RAM helped, but it was still slow. What dramatically improved the system's performance was replacing Windows 10 with Linux Mint running Cinnamon. Suddenly my ThinkPad became pleasant to use.

By comparison, I have absolutely no issues with Windows 10 running on my 12-core Ryzen 3900X with 64GB RAM and a PCIe 4.0 SSD. But that's high-end hardware.
