Usually (on laptops anyway) setting the performance governor only marginally increases performance and/or latency, while massively increasing battery usage. This is because the default behavior of ondemand governor is, almost always, to go to max clock speed practically instantly when there’s actual work to do.
In theory it can even have detrimental effect, especially with passive cooling (which I assume an Android tablet would have), because the CPU will throttle automatically if it gets too warm, and disabling power saving features means it’ll run generally hotter.

Thank you for this insight! Before setting the scaling governor, I did some initial testing that showed exactly what you’re saying: whenever I switched windows, fired up another app, wrote to a file - really whatever I tried - the frequencies maxed out. Maybe, what felt marginally snappier was the result of the CPU not having to jump between frequencies? I have zero knowledge on how CPUs work with power… 😅
