How Does Caching Improve Drupal Site’s Performance?

After a user accesses a web page on your website, content elements, and web data from that particular page such as images, HTML, CSS, etc., are stored in an accessible location. When that user visits the same webpage the next time, your website provides the user with the cached version of the content. This leads to reduced bandwidth and faster page loads

If you’re new to Drupal website development, it is always wise to hire Drupal developers to get the job done.

Here’s a list of 10 best Drupal caching practices to optimize your Drupal site’s performance.

10 Best Drupal Caching Practices to Speed Up Page Load Time

Tip 1: Make Use of the Internal Page Cache Module to Cache Pages for Anonymous Users

Let’s say you have an ‘Add to Cart’ option for anonymous users on your eCommerce portal. You can use this module to precisely cache this functionality. This Drupal performance optimization technique will take you less than a minute to set up and optimize.

Tip 2: Choose the Right Tools for Heavy Traffic Drupal Sites

If you running a busy Drupal 8 website, you need to choose the best suited caching tools to improve your site’s loading speed.
Here are some of the powerful Drupal caching tools and optimization techniques that you can try:

  • move to a Drupal-specialized hosting service provider like Acquia or Pantheon
  • shift your database to its own VM/container in case you’re still running it locally, on your Drupal web server
  • upgrade to PHP 7.1.0
  • Enable OPcache via php.ini.
  • Put a proxy (i.e. Nginx) in front of your server

Tip 3: Apply Block Caching Technique

This is the quickest and easiest Drupal performance optimization solution that can significantly increase Drupal 8 performance.

You simply need to cache those blocks that are not updated frequently like from one user to another.

Tip 4: Use Views Content Cache Module to Update Based on the Changes Made to the Content Changes

Views Content Cache module allows you to expire views caches every time you update or remove content on your website. This Drupal caching technique helps you to cache blocks that appear on thousands of pages, thereby optimizing your website for better performance.

Tip 5: Use a Reliable Content Delivery Network

This is the most powerful Drupal performance optimization solution for your Drupal website.

Here are the two strongest reasons why you should consider using a CDN to cache the static content including files, CSS, images, JavaScript, fonts, etc. on your website.

  • Since your CDN has endpoints worldwide, you can keep the network delay to a minimum.
  • You can speed up page loading time because your CDN has a domain different from your website’s, therefore, web browsers load content requests to your domain in parallel with the content delivered from your CDN.

Tip 6: Enable Varnish Cache (i.e. Front-End Cache)

This is another essential Drupal performance optimization technique that you can use to speed up page load time of your site. Varnish Cache can reduce the load on your server. How? It stores the HTML response, so the next time that particular page is requested, it serves it from memory. This results in bypassed PHP and web server which ultimately improves page load time.

Tip 7: Use the Advanced CSS/JS Aggregation Module to Boost the Front-End Performance of Your Drupal Site

Aggregating your assets together is the most straightforward and cost-effective way to resolve those Drupal performance issues on your site. Drupal’s AdvAgg module takes care of all the steps that you need to take to aggregate your CSS and JS files, right from file grouping to caching to compressing.

If things seems difficult to you, it is always better to approach a professional Drupal development company for their Drupal website development and support services. Drupal India is always ready to help you overcome any hurdle that comes your way to optimize your Drupal performance.

Tip 8: Install Memcache to Keep Your Database Load to a Minimum

You may be often struggling to reduce the database load by caching database objects in RAM.

Memcache is a great Drupal 8 performance optimization technique that helps you reduce that load on the database and speed up your page load time. It does it so by taking standard caches out of the database and by caching the results of resource-intensive database operations.

Tip 9: Enable the Entity Cache Module to Cache Entities

The Entity Cache module helps you cache entities. For better results, you may pair Entity Cache with the Entity Cache Loader Module.

Tip 10: Use Distributed Cache

Here’s another highly-effective Drupal performance optimization method to try. Once you’ve installed a distributed cache, it’ll store your database’s cache tables (Drupal’s “cache_” tables) either in file or memory.


So, these are some of the best Drupal caching practices that can significantly speed up your page loading time. If you’re not sure which technique to try first, you may hire Drupal developers who can handle all these caching settings.
