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).
