Strange. With the exception of electron apps (which are slow everywhere), I've found my M1 mini to be extremely responsive. Much moreso than my 16" mpb.
Affinity Photo starts in 15 seconds on my M1, which IMO is not okay. It's just as slow as on my Haswell Intel Mac. Everything else launches in a second or so. Spotify (Electron) draws a window in three seconds, but takes another four to display all content.
I have the 8GB M1 as my daily driver, the only apps that take a long time for me (but NOWHERE NEARE 15 seconds - maybe close to 5, but I'm not counting) are visual studio Mac (which is probably rosetta), Unity (which IS rosetta) and blender (also rosetta).
I don't know why this was downvoted. You see what you see. Maybe my experience with electron is tainted :D
I don't have any measurements, and I'm not really going to take any. It's just always felt slow. So I'll admit I should've perhaps been less prescriptive.
8GB M1 Mini, so maybe that makes the situation worse.
