The device is basically rendering each internal file and then displaying a window in that as it you turn the page. The bigger the internal file (more word, tags etc.) the longer the rendering takes and then displaying the page of text. And, the further into that file, the longer each page turn takes. I have a 3.7million word book that is broken nicely into about 800 chapters. Reading that is no problem. The page turning speed is the same wherever you are in the book. But, for testing, I merged all internal files into one file. It would open, and paging at the start was OK. But, if I tried to go to a page near the end of the book, it could take minutes. I did this a while ago, so I don't remember the exact details.

But on the other side, for pdf reading/searching makes some difference?
As far as I can see, the Kobo device do a good job of rendering PDFs. If you get a PDF that was designed for a page size similar to the device, it work well. But, most PDFs are designed for A4 or Letter paper sizes. That means you have to zoom in to read. And the navigation when doing this is terrible. It is slow and uncomfortable, and rarely worth it.

I've seen that at some moment you mentioned "maps" but I do not know what kind of format file they are in...
For "maps", I assume the mention is related to maps in books. The format of the map doesn't matter as long as it is a legal format in epubs. When you read, the map, or any other embedded image, will be displayed according the the tags used and the styles applied. The only other affects they have are that they make the book larger, and might make opening them and turning the page slower when they are to be displayed.
