Performance and Scalability

A low-level utility module which facilitates entity edit forms which do not attach field forms by default, but rather allow the user to select which fields to edit. This is useful when an entity type has many fields but where individual entities populate relatively few of them.

This module provides no UI overrides or configurability on its own. It is designed to be used by other modules either for their own entity types, or to override the edit forms of existing entity types.

This module provides a single function:

This module provides an alternative field storage backend. A table is created on a per-entity-type basis. All fields for each entity (well, those using our storage) are stored in one big serialized field.

This substantially reduces the number of database tables and database queries. It is an alternative to the caching approach offered by entitycache.

Provides drush commands to index fast with search API (using all your CPU cores).
It's an effective multi-process approach by spawning new drush commands that handle queues.

If you have a 10k+ node-set, this is highly useful.

Relies on drush and unix/linux-based systems.

Controlling search_api_fast examples:
Drupal 8 (settings.php)

On Drupal 7 we could disable hooks while running migrations:

https://www.drupal.org/node/2136601

This module adds a similar feature. You can disable hooks
in settings.php or by editing configuratoin object `migrate_booster.settings`.

There are two ways to disable hooks:

1) Disable specific hooks and modules:

Features

This module provides a Drupal 8 Queue API adapter.

Requirements

It is based on the php-rdkafka PHP extension for PHP 5.6 and 7.0, which is itself based on the librdkafka library.

It has been developed and tested against Apache Kafka 0.10, and should work on 0.9 too.

Utilize the Sucuri Cloud Proxy API to clear your Cloud Proxy cache from within your Drupal administration panel.

This module allows to delegate long-running tasks to external services, such as node.js applications.

Examples of long-running tasks: e-mail notifications for all the users of your site, big data processing, web crawling.

This is API module, you have to create the code for your tasks (both Drupal part and external service).

Pantheon Advanced Page Cache module is a bridge between Drupal cache metadata and the Pantheon Global CDN.

Menu module creates new blocks for every menu
.. and there's no easy way to remove them.

These automatic menu blocks are irrelevant when using Menu Block module, or modules like OG Menu, and as such they will just clutter the admin UI and even cause performance problems in some admin areas on sites with many menus.

Provides integration with Cash, an absurdly small jQuery alternative for modern browsers (IE9+).

Cash is a small library for modern browsers (Chrome, Firefox, Safari and Internet Explorer 9+) that provides jQuery style syntax for manipulating the DOM. Utilizing modern browser features to minimize the codebase, developers can use the familiar chainable methods at a fraction of the file size.
100% feature parity with jQuery isn't a goal, but cash comes helpfully close, covering most day to day use cases.
