Based on their description, this sounds like they rewrote ananicy in rust and added some kernel tweaks. I worry about NIH syndrome, since ananicy already exists and the other optimizations described could literally be done with shell scripts and udev rules. But it’s a nice idea and tbh actually very useful for low-end hardware.

I use more or less exclusively low-end hardware and for laptops/desktops without a lot of oomph being able to intelligently parcel out cpu time to applications that are actually a priority for the user is pretty important.

This kind of optimization is probably useless on anything approaching decent hardware, however.
