@Boing-ball I don’t recollect any speed ups for 3.1.4. Unless you upgraded from 3.9 which was a real resource hogger.
It's all relative! In a sane world where everyone felt a 030/50 was now a good and proper minimum spec, OS3.9 is fine! Why the hell we are still catering to the bog standard 68000 at 7MHz brigade in 2024, I'll never quite understand!
