Gnome feels frame-droppy and janky and things that should be instant take a while. Plus the nutty levels of system resource use. I assume that’s all the JavaScript (it certainly wasn’t like that before) since that’s often what happens to platforms that start using or are based on JavaScript, but maybe it’s not.
I'm typing this on Fedora 41 (Gnome 47, the latest drop, totally stock no extensions) on a nearly 10 year old 8GB/i5 Thinkpad X1 Carbon and it works just fine. If anything it feels like Gnome has gotten faster with the last few releases.
