Required by Braintree Integration module.

This module, having an insight into your Drupal installation, generates an insight about your site using Loader.IO API

Sample API:

curl -X POST
-H 'loaderio-auth: API_KEY'
-H 'Content-Type: application/json'
--data-binary '{"test_type":"cycling", "total": 6000, "duration":60, "urls": [ {"url": "http://mysite.com"} ]}'

EventDispatcher provides integration with Symfony EventDispatcher component for Drupal 7.

This module speeds up Drupal sites by collecting all watchdog entries in memory and writing them on shutdown in one query.

This module adds a hook_watchdog_alter. Used in DBLog Booster.

LCache is a module that applies the tiered caching model of multi-core processors (with local L1 and central L2 caches) to web applications. This allows scaling cache read access independently of network throughput. The current production implementation uses APCu as L1 and the database as L2.

Requirements: PHP 5.6 with APCu 4.0.11+ or PHP 7.0 with APCu 5.x.

Chained Fast is (another) port of the chained fast backend for Drupal 7.

To use, you can for example use Database + Memcache or Database + https://www.drupal.org/project/apcu.

This is a very simple/generic backend module for Authenticated User Page Caching (Authcache), providing the basics so that it be used to feed upstream reverse proxies and CDNs.

There's really nothing extraordinary on the code, it's a dumb authcache backend which only provides a cookie with the key that you can use upstream.

This module provides a framework for setting cookies that works well with page caching. It does not do anything on its own, but rather provides an API that other modules can use.
