GitLab is awful and slow at rendering large changes. Sometimes when folding and unfolding files, the scroll position will jump around (though I'm unsure if that's a browser extension). And when viewing standalone files, KDE's Invent GitLab server is slow and can take 5-10 seconds to render a few thousand lines and send it to the client as JSON with syntax highlighting, before the file contents show up.

So’s github, anything of a non-trivial size it just won’t show by default and you need to re-request every time.
It starts struggling around the kloc scale, and the browser itself soon follows as the dom is not the neatest and you start getting tab memory above half a gig, which I assume also makes the JS start killing itself or something.
