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… 😅

Yeah could be. There’s some latency for sure, the question is whether it’s noticeable. Definitely hard to tell subjectively, and as far as I know, also hard to measure without special equipment. I just think it’s probably not worth it to use the performance governor, even for (say) a laptop connected to a power supply, just because of the extra heat, fan noise, or the potentially earlier throttling. But I guess you have to judge that for yourself.
