I picked a random article from my browser's history, linked below. Just loading the snapshot year pages took about 10 seconds, then the snapshot hover took another 10 seconds. Finally, fully loading the snapshot page took about 50 seconds. So that's roughly 90 seconds to go from inserting a URL into the search bar and actually having the rendered page. Not unacceptable, but certainly slow by modern standards.
The original comment was "the Archive is painfully slow", the reply to that was "for me it's always quite fast", so I gave it some actual hard data explaining that 90s is in fact quite slow and maybe even painfully so in 2021. I have absolutely no idea how you got from that discussion to a hypothetical where the Archive doesn't exist. Obviously 90s is better than it not existing. I even said in my comment that it was not unacceptable.
I find it crass to gripe about Archive being slow. It's still much better than nothing. If folks want it to be faster than can donate rather than gripe, eh?
Good for you. Seriously (no joke, no sarcasm.) Good for you, that's awesome. (And yeah, that was the obvious question: "Have you tried giving them money?" but I wasn't feeling quite that salty.)
Still, I strongly support the work they do and think it's very important work. I also think they do a good job for their size and resources.
