Drupal is one of the most used CMS systems in the world. Not only is it highly secure, but highly scalable due to a myriad of plugins available for download that help to boost its performance and speed of code compilation.
Not only that, these Drupal modules adds to the existing functionality of Drupal and enhances its usability even more.
Here are some Drupal modules that you should install with your Drupal installation in order to make it more robust and streamlined to manage any amount of content that needs to be uploaded.
Boost is a plugin that helps to manage static page caching inside Drupal that gives Drupal a significant performance and scalability boost especially for websites that witness a lot of anonymous traffic. This is the best option in case you are opting for shared since it improves performance and multiplies the scalable code architecture of the coded pages.
2) Memcache API and Integration
This module integrates Drupal and Memcached to help merge the APIs of Memcached and the PECL libraries for easy use with Drupal and observe lots of tests on your CMS’s memory management potential.
Here is an example of a Memcache backend test:
Sessions (memcache-session.inc) (D6 only)
3) Hierarchical Select
This module helps to define the “hierarchical_select” form element which helps users select various items in a hierarchy with ease. It also helps to save selections that you have been making from the starts or the ‘deepest selection’ in order to force the user make selections as deep as possible in the hierarchy tree.
It also supports the labeling of levels so that you can limit the amount of items that can be selected at a time. A unique feature is the ability to create custom items and levels through this module. You can also select titles for the drop box where the selections go in and choose site-wide animation delays until the drop box gets filled with the selection.
4) Entity cache
This module helps to put core entities into the Drupal API cache. Since it has no user interface, enabling it will begin caching of all entities and stopping it stops the process. The entities it supports are: Nodes, Comments, Taxonomy terms, Taxonomy vocabularies, Files, Users. It also has support for custom entities or contribs.
5) Cache Expiration
This module helps to configure actions that will expire certain URLs from the cache like a reverse proxy cache or internal cache pages. This module can now be integrated with these modules: Boost which deletes expired webpages (files) from the main file system, Varnish which integrates over an existing administrative socket, Purge- which expires any dead or empty URLs and Acquia Purge which allows any Drupal website being hosted on the Acquia Cloud to seamlessly automate the purging of pages from their load balancers.
6) Advanced CSS/JS Aggregation
This module supports the On-demand generation of CSS/JS Aggregates especially when a file does not exist. It also features stampede protection which uses locking techniques so that requests for a same search will result in only one search thread.
The button on the bottom of the admin page will turn of aggregation. When a page is fully cached with CSS/JS assets, the file will experience zero file input/output that leads to better page generation and no downtime lag.
It also supports Gzips so that all the aggregated files can be compressed into a .gz format.
7) Varnish HTTP Accelerator Integration
This module integrates your Drupal site with the Varnish HTTP Accelerator which is a superfast reverse-proxy system.
With the help of Varnish, handling of static files or anonymous page-views without any login is handles with ease and your site performs faster than an Apache server.
Since it comes with admin-socket integration, it is now possible for Drupal to invalidate any cache entries and query the Varnish interface for the purge status.
These modules are a must-have for developers of CMS professionals who handle a lot of content and these modules help to automate a lot of tasks that would have required CSS or JS coding at the basic level.
