Get Better Desktop Responsiveness Under Heavy CPU Load Using CFS Zen Tweaks

CFS Zen Tweaks is a bash script and systemd service that tweak the Linux CPU scheduler for better desktop responsiveness when under heavy CPU utilization.

The default kernel settings are not tweaked for desktop usage, with high throughput being prioritized over latency, notes the CFS Zen Tweaks author. This results in a less responsive desktop under heavy CPU load. Using CFS Zen Tweaks, you should notice an improved desktop responsiveness – for example, its author mentions that before using this, YouTube would lag while compiling code, and that’s no longer the case using the CFS Zen tweaks.
