Drupal is a content management system which has been appreciated by the developers and users all around the world. It is the best content management system as compared to the content management systems which are available in the market. Off late there have been issues regarding the speed of the website. When Drupal is known to be the best among all content management system naturally, people expect a lot from it in terms of speed of the website, the templates available etc.
Any website which is new and has limited number of resources uploaded will be fast at the starting till you load it with images, videos, text etc which are not required. Once your website has all the heavy files onto it, despite of the powerful content management system with which you have made your website, it will be slow.
Drupal is no exception for it. Drupal is the content management system that is actually fast. It must be the data on the website, which would have made it slower to such an extent that you may not even be able to load the site.
Here we are going to discuss about what exactly reduces the speed of Drupal website.
Configuration of the Server
Drupal is a heavy-duty content management system and it would need a heavy-duty server, suiting the requirements. If your Drupal site is running on a normal server it is bound to be slow. You will have to get rid of the server with low memory if you are planning to have a website with images, text and videos.
Choose a hosting company which can scale your server requirements. Consider changing your web host in case you are facing problems scaling memory with increasing page size and visitor count.
Most of the hosting companies have database servers different than the site servers; this minimizes expenses on the hardware upgrades. This might be a major reason of slowdown as your website is dependent upon two external resources and any simple or complex query would take double the time which it would have taken in case of a single server.
For simple websites and not so complicated queries you may not notice the slowdown. But for the complex queries you may find that the website has slowed down to the maximum extent.
Usage of External Resources
Facebook feeds, RSS feeds, the tickers, countdowns and many more are the external resources that seem tempting as it makes your website lively. But these extra resources are the cause of slowdown and should be used very carefully. As the site loads, it has to gather lot of data from the parent sites of these resources, resulting in slowdown of the website.
Types of Users
Knowing the types of visitor and the pattern they establish during recurrent visits also helps you determine the long loading time, the measures which should be taken for crashing etc.
While Drupal even registers anonymous visitors through basic queries, it does not have to put efforts to personalize anything as the visitors are just visiting the website.
However if your website has many number of users who are not only visiting your website but also using the interactive options provided by the website, and if such usage is not planned during the making of the website, then there is no doubt about slowing down of your website. Here, you will never be able to blame the capability of Drupal and you may never be able to say that Drupal makes your website slow.
The number of users, their usage patterns and connections should be thought carefully during the initial stages of website design. If this is taken care the primary problem related to the speed of the website may be considered resolved.
Handling of Images
Loading the images on the new pages might take a long time if not programmed correctly. If the image thumbnail is generated every time the page loads then the website might take a longer duration to load.
There can be noticeable issues on performance if the webpage loads thumbnails as it is opened.
There are many tools available on the Drupal website for optimization of the speed. A module called Captcha module helps you stopping all the spam which is routed to your website from one or the other way. There are many more tools which are available for taking care of cache the website generates. All these tools are available on Drupal’s website.
Going to the basics for speed optimization, it is a very well known fact that if you ignore small aspects of the website speed, then you will have to work really hard to roll the ball again for improvising the speed of the website especially because it calls for backtracking.
