# CFS ZEN tweaks

## Description

The default CPU scheduler in the mainline Linux kernel

is [Completely_Fair_Scheduler (CFS)](https://en.wikipedia.org/wiki/Completely_Fair_Scheduler).

The upstream default settings are tweaked for high throughput which make the desktop applications

unresponsive under heavy CPU loads. This project contains a script that sets the CFS to use same

settings as the [linux-zen ](https://github.com/zen-kernel/zen-kernel) kernel does.

## Getting Started

### Dependencies

Runtime dependencies:

* bash

* gawk

* systemd (for systemd unit)

Build dependencies:

* cmake

### Installing

Available on [AUR](https://aur.archlinux.org/packages/cfs-zen-tweaks/).

Also see [releases page](https://github.com/igo95862/cfs-zen-tweaks/releases) for built RPM and DEB packages.

You can also build from source using cmake build system.

### Enabling systemd unit

Tweaks can be applied on boot using provided systemd unit.

```

systemctl enable --now set-cfs-tweaks.service

```

### Secure Boot

If you have Secure Boot the script might not be able to run. [See this thread for directions.](https://github.com/igo95862/cfs-zen-tweaks/issues/3)

## Version History
