I rooted with Kingroot together with the PC. It basically uses known exploits.
I heard it isn't that good and might be spyware, so I'll replace it with SuperSU later on if/when I have the time. Also thought about pulling .img files when running the stock rom to integrate magisk into them if possible. (Don't know if it is, I don't know much about Android yet)

I directly echoed the appropiate values into the proper /sys/devices/... files, it is linux after all. :-D Quick google brought up an free app called the "Kernel Adiutor" but I have no idea if it's good or not.

I have not much experience with mobile devices, I only have my smartphone a few months now after resisting for a long time and kinda got hooked on the whole mobile thing. Apparently the interactive scheduler is standard for many mobile devices, it has a lot of values to tweak and I played around with it a little earlier. The Tablet can clock down up to about 1.6 Ghz and all the way down to 126 Mhz (where it is most of the time with default values) and even when tweaking the interactive governor to be more sensible and clock up quickly when the load goes up (by using interface elements, for example) in my tests 126 Mhz just simply doesn't seem to be enough to have it feel responsive. The best results in responsiveness so far you seem to get if you set the minimum CPU frequency to 408 Mhz. The ondemand governor seems actually to be a little too aggressive in regards of keeping the clock up to maximum frequency, the same with the conservative governor. Would have to pull up a datasheet (if there is one publicly available, hadn't time to check) to see if the energy impact is actually all that critical, with lots of SoCs it kinda doesn't matter as long as they don't run at max clock all the time.

So far I haven't really noticed any massive issues regarding the battery life which seems already very tablet-esque and bad to begin with. The SoC this thing has is kinda slow and entry level, I'm actually surprised the battery life is as bad as it is. Feels wrong for a Battery that is allegedly 4000+ mAh, somehow - especially considering we only have an eInk screen to feed. WLAN seems to be the worst offender regarding battery life and will suck it dry in no time. I have honestly to say I'm a bit disappointed of the device and how it is put together, for how expensive it is. If there was anything even remotely comparable which would allow me to do Linux stuff and remote connect to my servers, I'd return the thing tomorrow. I saw the Dasung (sp?) paperlike screen but that thing is even less capable and more expensive.

EDIT: The temperature sensors of the battery/CPUs also don't seem to work correctly, they always read out temperatures between 18 and 19 degrees celsius. The room the tablet is in is warmer.
