tl;dr EEVDF CPU scheduler that has replaced Linux’s previous default scheduler (CFS), is close to completion. CPU schedulers can have a significant effect on performance and latency of various tasks.
It will be interesting to see how it compares to BORE which is what I use on my desktop systems. There’s also the many workload specific schedulers that sched_ext allows for, but it’s still not in mainline I believe.
I still compile my kernels with BORE. Based on the graphs I’ve seen, you still get a slight edge in framerate in games, and on-par performance for everything else, which is exactly what I want. Otherwise, you really cant go wrong with EEVDF at this point
