I don't think the OS is particularly slower, in many ways it handles modern hardware a lot better. I notice two particular effects of poor latency which I think contribute to the times when things are appearing to be slow.

1) Applications that aren't native and especially electron apps or similar. These are terrible slow to start since they are pulling up an entire browser environment to display their interface and they tend to start slowly and often run poorly. There are a lot of them about now.

2) CPU power profiles where the CPU is sat at idle and zooms up to boost speed can take quite a while for some reason and this causes a lot of Windows effects to miss a frame and getting janky. This really depends on your processor and power profiles and core parking settings but its bugged me for years that processor power saving is clearly not just free and one area you notice it is when going from idle to launching apps or doing something UI wise that has a lot of movement.

But generally I don't think Windows is much slower. It uses more RAM and drive space and it really can't be run on anything but an SSD now but power saving consequences combined with inefficient apps is mostly where I notice its not smooth.
