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?
Less than the cost of the power of running a 35 year old CPU for a year I’m pretty sure. They still have to pay for electricity in the third world. And wages. If your employees take a bunch of extra time to do really simple things on the computer, that also costs money.
Could also probably get a couple grand for a working i486 PC at this point, it’s a museum piece.
