Computers have gotten much faster since 2009, but I wanted to experience the original pain, so I made Firefox translate it offline. It huffed and puffed for a few minutes on my weak corporate VD, and it was strangely satisfying.
I still use an older firefox - the thread loaded in less than 10 seconds - I'd say 7 or 8. Maybe they've sorted loading issues, or changed their JS and APIs source / sets. I have an older computer that would have been newish in 2009, so IMHO nothing to do with old computers.
