Speed ​​up a page with huge text?

Question

PHP

I have a page, and a file with text weighing about 15 mb is inserted into it
, are there any options to somehow speed up this process?)

Answer 1

On the back, split into smaller fragments and load dynamically as you scroll to the end of the document.

Answer 2

Is it directly inserted into PHP? Do you want to speed up the loading of the main page?
Use XMLHttpRequest/fetch.
