Performance and Scalability

Boost cache cleaner flush (delete all the static boost cache pages) when any update occurs in drupal core. Example node update, insert or delete. No need to wait for expiration the cache or no need to run the Cron job.
There is no configuration required for this module only we need to enable this module and boost module should enable.
Boost Cache Cleaner does not work for anonymous user.

This module integrates development with Meteor (http://meteor.com/) and Drupal. Meteor is a platform built on Node.JS. Using Meteor, you can specify the layout and basic rules for your data and then let the underlying tools handle real-time updates between users (for example publishing a change from one user to other users, and refreshing everything on their screen that depends on that data). Meteor automated the basic infrastructure tasks to make it easy to built apps with real-time communication.

Creates a method that lets you programatically (through AJAX) increment a node's count in the node_counter table using memcache and cron execution.
This module is for sites with huge volume of visits which need get access content statistics, and can't update database with every visit by a performance question.

Public files URL is an extremely light weight module that allows you to override domain your public files system uses by extending the public file system wrapper in Drupal Core.

This allows you to serve your public files assets from an alternate, cookie-less domain which will improve upstream reverse proxy cache capability and improve concurrent browser HTTP request rate.

This module doesn't not alter the file system in any way. The alternate domain you point to should ultimately able to serve the same files from the same location as the normal site domain.

This module allows for hook_expire_cache() to be executed through a cron queue worker.

The module has a purpose to offload the request from the writings watchdogs directly into MySQL (Database logging core module). Instead of this the module will send the message to the RabbitMQ server and other process (consumer) will store the message into database.
You can start the consumer on different machine for example which gives you scalability.
With other words the functionality expand the Database Logging module to support asynchronous requests.

The project depends on following modules:

Module qui supprime les groupes dans les fichiers css/js pendant l'optimisation des fichiers et permets de les fusionner encore d'avantage. Cela diminue le nombre de fichiers à télécharger

Navbar Flush Cache is a module which adds functionality to the Navbar module allowing users to flush the cache from the menu. The module is based on the functionality provided by the Administration Menu module which also allows users to choose which part of the cache to flush.

Installation

1. Install and configure the dependencies. Check their README files for details.
2. Install and enable the Navbar Flush Cache module.
3. Define permissions on the admin/people/permissions page.

Borrowed pane allows grouped caching and client-side re-use of rendered elements on a page.

Use cases

Grouped caching

When using mini-panels it is ideal to cache the entire mini-panel rather than cache the individual panes within the mini-panel.

The problem is that the mini-panel often contains one or more panes that are unique to the current page via context, the current page path, current user, etc.
