There is no doubt that memory is the fastest, but can hundreds of M of data be stored in it? This is not the case In reality, of course, sometimes it is temporarily placed in the server cache. For example, if the ob_start() cache page is turned on, the page content will be cached in the memory before sending the file header, until the page output is automatically cleared or waiting for the return of ob_get_contents, [or Cleared by ob_end_clean, which can be well used in the generation of static pages and can be well reflected in templates
