But what does that have to do with Kobo?

I am not sure how exactly the Voyage used to do it (and I no longer have a functioning to test), but the Oasis 2 prerenders the next page(s) ahead of time. The way it looks like about a whole chapter. If you flip through as fast as you can, then the Oasis stutters a relatively long time at a chapter mark where a full refresh is triggered. Fine, so it is the flash, you might think? No it is not. Go to the end of a chapter and wait a little bit for Oasis to catch up (maybe 2 or 3 seconds) and then turn the page, it is near instant again. There is no delay from pushing button to do the refresh. In the normal use case when you actually read the words before turning the page you never have to wait.
So the bottleneck is the cpu and rendering the page on the Oasis 2, and not the eink itself. The speed improvements over a Voyage can be safely attributed to a faster eink controller if the Voyage also prerenders. And here the comparison with Kobo becomes relevant. If all Kindles are snappier in comparison, it is very possible that they always been prerendering at least the next page. Apparently a Kobo does not prerender pages, but does them on the fly for standard epubs and maybe even kepubs.
