There were no surprises in Blender, Python, PHP, or SciKit-Learn performance.

And the newest test profile, Aircrack-NG, didn't show any changes besides powersave leading to much lower performance.

Overall no real upsets in the results. Switching from ondemand to performance for CPUFreq can yield a few percent improvement in performance for select workloads while the rest of the time it continues to deliver similar performance. The only scheduler leading to a dramatic slowdown in performance is powersave, but it's sole purpose is to save power by sticking to a low power state.
