They are pretty fast on my PC and I don't even have an NVMe SSD

  I was just doing it on my Windows box and it maxed out the hard disk's IO for about an hour. I don't know what it was doing in the background, but, compared to what it was downloading, it was a surreal amount of work. It's understandable Windows updates take longer because Windows offers the guarantee that a file path will always point to the same while the machine is running, as opposed to Unix environments where they only guarantee your file pointer will point to the same file. This makes upgrading a running machine a bit more complicated than replacing files from under running processes. I'm not even sure how I would implement such a thing. Probably file system overlays and collapse them on reboot.

    It’s imposible it maxed out your IO for an hour unless you have a mechanical disk.

      It has a mechanical disk. It’s the machine I use to test and build things under Windows. Still, it’s crazy when compared to the sister box that’s identical but runs Ubuntu, which remains usable through the whole upgrade process (and takes a lot less time unless it’s a full OS upgrade)
