If you try to unzip a epub you will see that each chapter is a separate html-file, but some publishers / authors put the whole book in one chapter / file. Most books is text only so it should not be to heavy on performance, but if the book contains a lot of images that could require more memory. One thing you try then is to override the browsers dom-parser and add a loading="lazy" on img-tags, take a look at this recipe:

Is there a way to not load all the pages of epub at once and for example 5 to 5 are loaded In the link below, there was a problem (https://github.com/gerhardsletten/react-reader/issues/170) ,according to which I found out that all the pages of the epub are loaded at once, and if the epub is long, it will slow down its initial loading.
