Hacker News comment sections are the only part of the internet that still feel "impossibly fast" to me. Even on Android, thousands of comments can scroll as fast as the OS permits, and the DOM is so simple that I've reopened day-old tabs to discover the page is still loaded. Even projects like Mastodon and Lemmy, which aren't beholden to modern web standards, have shifted to significant client-side scripting that lacks the finesse to appear performant.
The modern webbroswer trick of "you haven't looked at this tab in an hour, so we killed/unloaded it" is infuriating.
To be fair... Lots of people just never close their tabs. So there's very real resource limitations. I've seen my partner's phone with a few hundred tabs open.
I would like this feature if I had more control over it. The worst part is when clicking a tab that was unloaded which makes a new (fresh) web request when I don't want it to
In firefox it's possible to disable it: https://firefox-source-docs.mozilla.org/browser/tabunloader/ . Enabled is probably the reasonable default for it though.
Particularly if you have maybe 40 tabs open and 128GB of ram.
