Performance and Scalability

This module does one thing, allow an admin user to define and interval of time that must pass before another request may be made by a particular user agent. This is most useful in cases where a search engine bot, for example, does not respect the request-rate set in the robots.txt file and it's repeated requests are impacting on site performance (requesting old pages outside of any caching layer for example).

Baseline provides an extensible set of tests to get performance metrics comparable across different systems or configurations.

These metrics can be used as a baseline for comparatives, the goal is to get the closests results for a given test when external factors have not varied (system, load, configuration, database, etc).

Motivation

Performance benchmarking can be tricky (all the more in Drupal), and repeatability is the weak link of most benchmarks you find on the internet.

Stingray is a Drupal plugin that implements Stingray Traffic Manager through the SOAP API.

Currently it support below functionalities (Stingray Traffic Manager v9.0):

1. Clear cache by path pattern (clearMatchingCacheContent)

THIS MODULE IS UNDER HEAVY DEVELOPMENT AND NOT MEANT FOR PRODUCTION SITES.

OG can take quite a toll on website that rely heavily on it. OG cache tries to cache certain parts of OG for short periods of time, as to increase performance.

Allows the site administrator to specify a minimum length for autocomplete strings, to stop autocomplete from running SQL queries with potentially huge result sets.

It does this by replacing Drupals Drupal.ACDB.prototype.search function with a little function that checks if the user-entered string is shorter than the set minimum length. If so, execution is stopped and the back-end callback handler that provides completion targets is not accessed.

Infinite Comments replaces the default Drupal pager allowing comment to be pre-fetched into the same page.

Requirements

• AngularJS
• ngInfiniteScroll

This module is designed to work in conjunction with the Entitycache module. By default, entities are cached when loaded. This module pro-actively puts entities into the entity cache, resulting in a faster user experience.

This module allows users to purge the Varnish cache of specific URLs. It has 2 interfaces in the backend.

1. One interface is the Varnish Server Configuration (VSC). It enables connection and authentication to the Varnish server via port or secret key. You can also enable or disable the Varnish purge URL feature from this interface. After completing the configuration, this module provides varnish server connectivity status and alert notifications.

Riak is a key/value object store by Basho. http://basho.com/riak/

This module enables a new Riak backend for Storage API.

Alert! This could break your site!

About

This is a Drupal module that integrates InstantClick, a library that pre-loads links on hover, taking anywhere from 250-500+ ms off the perceived page load time for end users. It is currently in an alpha state. At this point it is mostly suitable only for testing/review by developers, but could also be used on non mission-critical sites or simpler sites once you've ensured that all functionality you care about is in fact working.
