I may not have been clear, Java was only really relevant for hosting onsite. Other comments in this thread mention competitors using other server-side languages that can be served from a RaspberryPi. The only way it'd slow down the client is if your server was poorly tuned or underpowered. In my own experience, managing Java applications have their own set of skills.

The client side bloat I've noticed are both in visual clutter and performance using the Atlassian hosted version...so I doubt it's related to Java (outside of maybe scaling issues?). I don't doubt they have a modern front-end. It feels like one of those hip, new, modern, chunky sites that take too long to load and I try not to revisit. I don't mean to knock on React or modern frameworks, they have their uses and fill needs, but the end result often isn't a pleasant experience. The version I remember using years ago was a bit slower than most static sites, but almost seemed boring and corporate in use (which is a compliment for something you rely on for your job).
