 * I’ve noticed using when using WordPress to edit documents that it automatically
   adds html comments like
 * > <!– wp:paragraph –>
 * .
 * I am not sure what the purpose of these are, but is there a possiblity that having
   this text in each page will slow down the render speed of the page in web browsers.
 * I remember some idea about avoiding blank spaces in documents because even these
   will slow down the download speed of a file.
 * Is there any way of stopping the automatic insertion of these comments?

 * Those comments are used to define the blocks in the block editor. They will not
   be output to the webpage or the feed normally, so will cause no slowdown in the
   browser.
