Today I Learned

Using another Linux scheduler called scx_bpfland, a scheduler its job to manage the load across multiple cores effectively. scx_bpfland is an alternative scheduler built on top of sched_ext.

Long story short, you can significantly improve Linux gaming by switching to another thread scheduler like scx_bpfland, which can improve the unstable 30 FPS (with spikes) to a very stable 60 FPS game play (video link).

I also would love to combine these scheduler with other features like CPU pinning. There is a Linux CLI tool called taskset, which seems to pin cores for processes.

In another unrelated software sidekiq, taskset was also used to improve performance due to CPU affinity which in result making the software so much faster.
