One of the most painful aspects of developing MuQSS for desktop responsiveness and interactivity has always been that all regular benchmarks are measuring things that are completely orthogonal to its target goals. Apart from testing if and how much they affect regular benchmark results, they do nothing for testing the target effects.
During my extended downtime away from linux kernel development I completely missed that Steven Rostedt had conducted benchmarks on MuQSS for the low power Google Chromebook looking for exactly that in 2023. He kindly alerted me to this work and an LWN.net article where it was discussed in 2025. With his permission I have created a copy of his presentation:
2025 OSM Scheduler Governors Presentation
This is a summary of the relevant original benchmark results from 2023 in these graphs. (Lower is better.)

And the full video of his presentation on youtube. The full explanation of these results is in the video from about 12:30:

He has opened an interesting discussion about resuscitating the idea behind his scheduler governors you can follow here:
