Performance and Scalability

There are a couple really good modules out there for periodic revision maintenance and keeping node revisions in check, namely Node Revision Delete and Node Revision Restrict. These modules aim to make regular maintenance of your revisions easier to prevent revisions tables from growing too large. Stop here and try one of those projects if you have fewer than half a million rows in node_revision.

First, we had drush_ecl (which is exclusively a drush plugin). Now, we'll have ECL. This is for those that want an actual module to integrate into their drupal project for loading entities into caches.

This module will resize uploaded images to be below the set dimensions. It is not an image style or other presentation layer module. If you want to maintain the original image you should use Image Resize Filter or an image style. The use case for this module is sites where users may upload very large images, but you do not want/need to keep the original.

This is different from the core image field size restrictions in that it will work on already uploaded files and imported content.

This module aims to provide better AJAX support for Commerce checkout pages as documented here, https://www.drupal.org/node/1329308. Currently this module applies to the standard checkout process & also includes an AJAX checkout block, yay.

Installation

Download and install the module as usual.

Configuration

Excluding block configuration; enable and the checkout process is now AJAX driven.

OpenStack Object Storage (Swift) is ideal for cost effective, scale-out storage. It provides a fully distributed, API-accessible storage platform that can be integrated directly into applications or used for backup, archiving and data retention. It's a part of OpenStack, a free and open-source software cloud computing platform. Which is primarily deployed as an infrastructure as a service (IaaS) solution.

This module provides a small "caching" extension to the Juicebox HTML5 Responsive Image Galleries module that allows the XML-based configuration for each gallery to be delivered via a local caching mechanism instead of being built in isolation.

This module makes use of an existing php resque implementation: https://github.com/chrisboulton/php-resque

This module extends DrupalQueue to be able to use DrupalResque instead, also being able to use DrupalResqueUnique so that jobs with the same payload key are not queued at any point in time.

Development of this module takes place on Github-

Drupal Static File Cache (SFC) module helps locking down critical cache Bins/CIDs while still allow for a Memcache/DB/[YourCache] fallback for data caching.

The static module generates a complete copy of your website in html form including all js, css, images and other assets. This can then be transferred to run the website from a simple web server without PHP, MySQL or memcache.

Drupal module to defer JS loading after a signal, it is a JavaScript Quality of
Service oriented module. This is useful to give some scripts priority in front
of others. This is not done to make the scripts load faster, but to make give
their XHRs priority against the deferred ones.
