I remember several decades ago when I dug into wine things asynch io was a thing there was a lot of discussion over. Apparently windows actually has a very robust asyncio interface that’s emulated with a bunch of epoll and other logic.
I believe a lot of games did tricks with this and the hacks sometimes had performance costs.
A quick Google says that’s still a thing being worked on and there’s a newish io_uring but apparently that has problems. So maybe that’s a place we can see improvements in the future.
