It's probably a generational thing.

The 20 last years, the web, the animations and the badly coded apps lead people to be used to slow software.

However, when you have used software for decades on much less powerful hardware, the sluggishness of all of it is kinda jarring.

This is true for me, as well. Whenever I start a 50 MHz computer and something is instantaneous instead of displaying a "Please wait…", or I start a modern computer with the Haiku operating system instead of Windows or Linux, I'm reminded just how responsive things can be.

On Android, I stumbled upon a file explorer, called Little File Explorer, that feels like this. It's 170 KiB, and generally opens directories without a feeling of transition. Instead of feeling like it's laboriously building a view, it feels almost like the view's already built. Alas, it doesn't yet remember scroll position when paging back.

Modern things can make stuff that would be slow, fast; but they also usually make stuff that can be fast, slow. I believe this normalisation of slowness is a "Normalisation of Deviance".
