Jira takes 10s for certain pages to load for me on a gigabit connection with an M1 Mac. I doubt a dial-up connection could even load a Jira backlog page in under an hour.

Same, but I'm not sure if that's because there's too much data or just because Jira is slower than a dead snail.

Funny you mention Jira, so you're saying there is no information after a day that requires you to reload?

Jira updates without needing to refresh.

I have a 10gb connection and I still see that. Browsers, despite being excellently threaded, are also poorly threaded. Who knew?

Modern websites are simply enormous and slow.
