Boost provides static page caching for Drupal enabling a very significant performance and scalability boost for sites that receive mostly anonymous traffic. For shared hosting this is your best option in terms of improving performance. On dedicated servers, you may want to consider Varnish instead.
- Once configured the Boost module, it will create a .html files in the root folder while viewing the site pages for the first time.
- In the second time if the URL hits, it will loads the page using these .html files. so, load time is reduced.
- we need to configure the bunch of codes in .htaccess file
- If we use the expire module. It provides expire the url from caches while create or edit nodes, taxonomy, users, pages, custom url.
