Performance and Scalability

Summary

Role execution time limit is a small module that allow you to set PHP max execution time per role and command line usage(drush).

Requirements

Permission to change max_execution_time on your webserver.

Configuration

Drupal 7

Go to admin/people/permissions#module-role_execution_time_limit to set the persmission.
Go to admin/config/development/role_execution_time_limit to set the limit for a role.

Share sessions between different domains! Not just sub-domain.

You have several different domains for your drupal site, they can be in different servers but using the same database server. You want users only need to login one time for all those domains/sites. This module would help you.

Ideas:
put an iframe into a custom invisible block, pages with this block would sync sessions to other domains/sites

Other keywords:
session sharing
distributed session

Security:
flood control
source control

Keep Frontend DRY; sprinkle it with Magic

(we demand to be taken seriously)

All Drupal sites need some magic, so give yours some! Magic is a set of tools for front-end best practices and general front-end goodies to make your life as a front-end developer happier. Features include:

A cache backend wrapper which lets you specify multiple cache backends in order of preference.

If one or more of your caching services are unavailable, this module will gracefully degrade to a lower priority cache service keeping your site running in case of a service failure.

This module is tested to work with the following cache backends, but should work with any module:

"The longer a piece of content goes without being modified, the longer its cache should be."
Here is the basic idea for this module.

This module provides a new reaction for context, which allows you to set (in http headers) :
- One "cache-control" & "expires" time
OR
- Different "cache-control" & "expires" time depending on how long it has been since a piece of content was last modified

Overview

The Postgres Signature module making all database connections and queries "personalized". If you have not only default database user but also SQL users with the names as Drupal users, all requests would be performed with corresponding SQL-user name.

Queries from user #1 and from anonymous users authored by default connection string.

Adding and removing Drupal users also leads to do the same on database level.

On administration pages there is a functional to create (or delete) in bulk SQL users to reflect existing Drupal users.

Provides a Memcache status and cache reporting page, accessible by a link on the status report page.

This module provides the same functionality for Memcache that APC Status does for APC.

Installation

Memcache Status requires:

403 to 404 is a simple module that emits a 404 error when a user tries to access a page that they don't have permission to view.

Drupal 7

Install this module like any other module and set the 403 page path to m4032404. You configure the module via one of the following methods:

A way of managing and displaying information using the bunny pattern.
