Linux 7.2 has landed, dragging x86 timing clean out of the nineties by making the Time Stamp Counter mandatory.
I wrote up a quick article on why ditching those ancient legacy fallbacks is good housekeeping, plus a few other bits like cache-aware scheduling and memory tweaks worth noting.
Is anyone still using legacy hardware? If so, what do you use it for?
No “poors” are running a 486. You would take the best part of and hour to boot a modern distro on a 66MHz (that’s 0.066GHz for you kids) 486. That’s if it would boot at all - which it likely wouldn’t.
