Performance and Scalability

AJAX Cache acts much like imagecache by generating the result of a request on demand and storing it on the filesystem for later reuse. This is useful if you are trying to scale a site that makes many dynamic ajax calls. AJAX cache saves results directly to the files so the web server can serve them directly, rather then bootstrapping Drupal.

AJAX Cache will do nothing by itself. Supporting code must call it.

How to use

First you define the presets you are going to use like this:

How does it work?

According to Wikipedia, "the data URI scheme is a URI scheme that provides a way to include data in line in web pages as if they were external resources." That means that rather than having a URL telling the browser where to find the image you actually have the image data right there on the page so the browser does not have to make an extra request to get it.

This small module is designed to help you performance-optimize your use of input filters and input formats.

D7 version now available.

Filter Check does the following:

Wondering why your views run so slow? Why after switching to InnoDB, MySQL isn't running any better? This module has the answers!

Indexes

It will show what CCK columns get used in a view filter or relationship and give you the option to add an index on it so the views query will run faster. Also can add indexes to core modules that could use one.

Engine

Ability to convert your database from MyISAM to InnoDB in order to eliminate table locks on data writes.

Do you want super fast file downloads from your Ubercart store?
Ubercart CloudFront module provides an easy way to generate Signed URLs for protected files hosted from Amazon CloudFront CDN.

This module integrates directly with Ubercart File module by doing a server-side redirect for the download link provided in emails and Files tab on user profile page.

This module is designed to help manage large multisite installations by allowing a master installation to run multiple slave crons when the master runs cron.

Roadmap

This module provides a really fast, secure and stable, lightweight CLI Daemon. This daemon exposes a simple hook in order for module to run actions using it.

Features

• Clean usage of pcntl_* extension, with SIG handling.
• Lightweight, it does bootstrap a Drupal in child processes in order to let modules benefits from hook_init(), hook_exit(), and a clean environment.
• Is able to run job_queue jobs, and Drupal cron if no other module has been run.
• Provide a Drush integration.
• The CLI Daemon can be run and killed by site administrator from the Drupal administration.
• Proceed implementing module list pragmatically, run the first found and dies after remembering where is its module pointer within the module list.

This modules is no longer being maintained.

Consider migrating to Advanced CSS/JS Aggregation

Context HTTP Headers provides a set of Context reactions that allow you to set HTTP Response Headers for each context on your site. It is a generalized framework for response header handling that allows the sending of any arbitrary header value(s).

Through the use of two provided hooks you can expand on the header capabilities and provide specific fields for configuring header returns.

The Akamai modules provides integration with the Akamai Content Control Utility (CCU) Web Service. This enables the purging of cached URLs in the Akamai Global Network in response to different site events. It purges not only the canonical URL for your page/node (node/123) but also any associated URL aliases.

The various mechanisms to clear Akamai cache are:
