Performance and Scalability

Introduction

Cache Consistent provides a transactional aware cache backend wrapper as a means of ensuring cache consistency in setups not using the database as a cache backend. #1679344: Race condition in node_save() when not using DB for cache_field

Cache Consistent works best with the database isolation level is set to READ-COMMITTED.
It CAN be used with REPEATABLE-READ, but will in this case only mitigate the problem,
not eliminate it all together. When configured for REPEATABLE-READ, there may also
be occasionally more cache-misses.

This is a demo module to for the upcoming Purge 2.x api. This module enables Purging of reverse proxy caches for the Drupal Shrubberies platform.
This is module is currently incomplete and should not be used on production shrubberies.

A Simple cache module that works for Anonymous & Authenticated users.

Stores the HTML of the whole page in cache table and serves it after Drupal core functions are executed, not requiring to process theme functions and thus saving time.

Pages are cached by URL & user role.

CloudFlare Purge (CFPurge) is a plugin for the Expire module which enables it to clear specific pages from the CloudFlare CDN when you update, delete or add a page.

CloudFlare with "cache everything" enabled provides the ultimate performance for your anonymous users, down to a 20 millisecond response time and extremely fast transfer rate. When you enable this setting your site can instantly handle millions of anonymous users, even if you're using a shared host.

By the way, Google also likes really fast websites, so it also improves your SEO.

This module is intented to maintain Drupal core caching for multiple device
types simultaneously through interception and modification of the requested URL.
It performs device detection using the Mobile_Detect class, provided by the
required mobile_detect module.

Mobile cache also provides the capability to switch themes for mobile (and,
optionally, tablet) visitors.

The caching method should be compatible with alternate cache backends such as
memcached as well.

Obsolete

This functionality is now included with Authcache. You no longer need a custom module for this.

What is this

Commerce Authcache allows the Drupal Commerce module to work with Authcache.

Adds contextual link “Clear cache” for:

• Blocks
• Views
• Panels
• Path Breadcrumbs
• Entity cache and Display Cache (for nodes only)

Adds link for clearing current page cache (Boost supported too).

Context Cache is module which lets you control caching and expiration through Context. For example, for one content type you can set its cache for two hours while for another content type you can set it for 30 minutes. In another use-case you can set an expiration of five minutes for the homepage and 30 minutes for any page in the news section. In case you use an external cache this module sets the proper headers for expiration.

This module includes an extension to the Node.js Integration module that provides an authenticating proxy.

The extension reuses the authentication mechanism shipped with the Node.js Integration module, and only proxies requests that are associated with an authenticated Node.js socket.

About

"In electronics, a shunt is a device which allows electric current to pass around another point in the circuit by creating a low resistance path."

Shunt module provides a facility for developers to create virtual "shunts" that site administrators can trip in emergency situations, instructing Drupal to fail gracefully where functionality depends on them.
