Core 2 Duos are slow, yeah. I’ve got an Asus F8SP-X1 laptop from ~ 2008 with a Core 2 Duo T9500, 4 GB RAM, and a SSD SATA drive in it. It was originally a mid-range Windows Vista system. Over its years I managed to upgrade it as far as it could go. It does run standard Ubuntu and Windows 10 - Certainly not fast but it does run. Performance would lean towards unbearable without the SSD. I suspect Gnome isn’t doing it any favors and switching to a lighter DE or distro would help (or maybe just ditching the DE altogether) but since it’s just a spare laptop it’s no big deal.
One of the takeaways from your experiment is if it the system was already crap at running Windows 10 it’s not necessarily going to fare better with Linux, at least if you’re expecting a nice desktop environment. I don’t know if in 2025 we need to equate the “will this run Linux?” challenge on old Windows XP/7 hardware aside from the geek/techie users that want to do something with that old hardware. Anyone else non-technical stuck with that type of hardware isn’t thinking about Windows 10 being retired.
Agree with you, SO is great for finding info. There are solutions on there for niche problems that I haven’t been able to find elsewhere, the type of thing where someone actually took the time to type out a step-by-step answer and it’s now there and searchable on SO. It’s a bummer that so many people seem to hate on the site nowadays.
And lets not forget the whole reason SO came out in the first place, back then web results were littered with question/answer links to sites like Experts-Exchange. I hated trying to figure out if an answer was on there, most of the time you ended up with a link to a question that you think has an answer but oh no you need to subscribe to view an answer that may or may not exist.
