It's a half truth.
I met PDF articles where even my 10" Galaxy Tab S4 (8 cores) suffered to load complex diagrams.
To get my point, please just try the InkPad X in read life on your own, and see that even a few pixels GUI update is horrible (everything takes 0.5 - 1sec as a minimum to be updated, seems like a constant penalty everywhere, except at pinch & zoom in factory software, they somehow made it well).

So there _IS_ something to fix, not exactly in koreader, but in the firmware to avoid those horrible UI updates, e.g. drawing a tiny black box at active buttons taking a 1 second!
Speed of complex PDFs is just yet another thing, I don't expect any improvement there (I have plenty of PDFs where not seeing it as a problem - moreover, PDFs can be preloaded in background while I'm reading... tablets doing the same, preloading is not instant there either...).

My suspicion, that the quality of InkPad X screen is hardcoded somewhere in the HW, and everything drawn at a too good quality (almost no ghosting), and/or updating a whole screen buffer even for a few pixel.
Compared to my Kobo 7" H2Ov2, where these updates almost instant, but in turn the Kobo has severe ghosting in general...

The reason I like koreader is browsing/searching functionality, quick jumps between technical books/articles (= need responsive GUI), and using gestures saves from a lot of GUI update penalty.
