My Osborne 1 took a minute to load Wordstar. Searching a document would take more minutes if it was longer than about 30k because it had to swap to floppy disk. Connecting to a BBS was time for a bathroom break. So were compiles.
I think most of what is perceptually slower for the author is that it's a small percentage of the 40 years it took to get here. I loved my O1 but it did what little it could do very slowly. My phone in my hands right now is doing a trillion more things better and faster.
