scx_rustland is Linux scheduler made of a BPF component (dispatcher) that implements the low level sched-ext functionalities and a user-space counterpart (scheduler), written in Rust, that implements the actual scheduling policy.
In order to use scx_rustland you need to install the latest Ubuntu kernel from this ppa: https://launchpad.net/~arighi/+archive/ubuntu/sched-ext
Please ensure that the following interfaces are connected to grant the scheduler complete resource access:
sudo snap connect scx-rustland:process-control
sudo snap connect scx-rustland:system-observe
sudo snap connect scx-rustland:system-trace
Also make sure that compaction kthread does not reclaim unevictable memory to improve scheduler's stability:
echo 0 | sudo tee /proc/sys/vm/compact_unevictable_allowed
The scheduler is designed to prioritize interactive workloads over background CPU-intensive workloads. For this reason the typical use case involves low-latency interactive applications, such as gaming, video conferencing and live streaming.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install scx-rustland, simply use the following command:
sudo snap install scx-rustland --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
