Drupal was launched in 2001. It is an open source content management framework written in PHP and distributed under the General Public License (GNU). It is used in appx. 2.2 % websites as a back-end framework and out of this 0.2% Drupal development companies used Drupal 8 for their websites. It has a wide number of applications from personal blogging to government and corporate websites.

Drupal in Wikipedia is well supported and comprises around 1.3 million members who contribute significantly by designing modules and adding to the functionality. Drupal is counted among the best CMS platforms. It has many advanced features and to program for Drupal you need a basic knowledge of PHP and HTML.

Drupal pitches as an enterprise web framework and provides drupal developers with a sophisticated API. In March 2016, Drupal 8 is launched with 200 features and offers new standards for building incredible digital experience to small enterprise and business.


Like any other CMS, Drupal has its own potencies and flaws but lets you optimize it to cater to your needs. For ensuring that Drupal runs smoothly, we have discussed here some of the best practices for perfecting the Drupal setup to make certain an excellent performance level.

1. Image Optimization

  1.  As per the recent statistics, customer closes the website if it takes more than 3 seconds in loading. However, images take most of the downloadable space on a web page so to speed up the load process you need to optimize the images.
  2. You need to diminish the load time without compromising the quality. You can compress your images with Drupal’s Image Optimization API. This API can optimize files on upload, an image effect in image styles and by scanning and optimizing. 
  3. You can also make the images the right size before upload. All the above methods optimize the images without compromising on the quality. Another valuable method is to consolidate pictures into a solitary picture document.
  4.  You can also use the CSS image sprites to accomplish this. Cascade Style Sheet image sprite lets you create a single image out of several images. This saves the number of server requests and bandwidth.

2. Cleanup Unused Modules

A best practice is to check which modules you truly require and to incapacitate unused ones, as these add to the aggregate overhead for extra PHP code to execute on every page load. Also, additional JavaScript and CSS documents are executed at page load time although they are not required.

When managing modules, the best strategy is to prepare and see what a module truly does and that it truly increases the value of your site. If you discover you have modules that are used rarely then it's a smart thought to incapacitate them and attempt to locate a substitute technique to accomplish a similar outcome.

The missing module is a very useful tool for detecting modules that are active in your database but not present in your file system. “Orphaned” modules further increase the load time.

Another way could be disabling the module rather than doing away with altogether because that way you lose the database information as well.

3. Cache

Caching is an instrument for the brief storage of website pages keeping in mind the end goal to lessen data transmission time and enhance execution. At the point when a guest touches base at your site the stored form will be served up unless it has changed since the last reserve.

You can use the Cache API for changing the settings related to caching. You can use the Context, Tag and Max-age properties of this API to control the cache settings. Drupal provides Page caching, Block caching and Views caching.

Page caching is enabled by default and caches pages for anonymous users. Block caching can be done in the render array returned by the block object’s build () method. 
Views are used to query the database. Pages which are requested by authenticated users may make a lot of queries to the database slowing down the page load process. So, views caching is a great technique in this scenario.

4. Content Delivery Network (CDN)

A frequent recommendation for enhancing website performance, whether that be Drupal or any other CMS, is to use a Content Delivery Network (CDN). A CDN is described as “an interconnected system of cache servers that use geographical proximity as criteria for delivering Web content.”

In other words, a CDN offers a way of taking the static files of a website, like web designs, images, and JavaScript and delivering them through web servers that are closer to the user’s physical location. Shorter proximity amounts to faster load time. Some examples of CDNs are AWS CloudFront, Cloudflare or Fastly.

There are many benefits of using a CDN:

  1. The use of CDN decreases the latency and speeds up the load process.
  2. The origin server can process more concurrent requests because the page responses are shared between the origin server and CDN.
  3. CDN accomplishes domain sharing by distributing responses across multiple servers and achieving greater HTTP performance.
  4. The page optimization service provided by CNS also boosts user experience.

5. Combine CSS & JavaScript File



Drupal performs aggregation and compresses CSS and Javascript files. If there are a large number of files there are a greater number of HTTP requests, slowing down the page load process. If a site takes longer to load, the visitors may leave the site before it loads. So, lessening the number of files will decrease the page load time and improve performance. 

Drupal has an Aggregation and compresses CSS documents that will take individual CSS records and connect and divide them into only a couple of records. This additionally accompanies a pressure part that will expel the whitespaces in the documents that fill no general need. By lessening the number and aggregate size of CSS documents, the general speed of stacking these records is progressed.

JavaScript documents can likewise turn out to be vast. Drupal CMS has a module that permits you to minify these records. Thus, you spare data transfer capacity, decrease time slack and inertness, and enhance the general execution of your site.

6. Working efficiently on different browsers and devices

You must not only optimize your site for desktop but for mobile phones as well. This is so because these days the majority of users use their smartphones to access websites. So, it is very important that your website is mobile responsive. This can be done through Google AMP module.

By keeping your CMS running easily and more adequately, lightens the anxiety and helps you concentrate on maintaining your business. Enhancing the performance of your Drupal website will also to help your business grow. So, when you look at the results you will be assured that it is worth the effort. You’ll be happy you did it!
