Most Popular Drupal 9 Modules to Enhance Website Performance
Improving your website performance is important for achieving customer satisfaction and ranking better on search engines. Your service provider, bad programming practices, a high number of requests to the server, improper server configuration, caching technique, and heavy videos or images can affect your Drupal website performance. Some of these issues on your Drupal website are on the surface and can be solved by installing the relevant Drupal 9 modules. Here are top 10 Drupal modules that will help you enhance your Drupal 9 website performance.
1. Site Audit
Site Audit is a Drupal static site analysis platform that generates reports with actionable best practice recommendations. The Drupal performance module uses a technique known as static program analysis. This mechanism does not actually perform requests on the target Drupal site, and in doing so avoids the observer effect. It's non-intrusive, so no installation into the target site or configuration is required. This helps you get fast and reliable reports and you can detect common problems and provide introspection into Drupal sites. Reports can be generated in multiple formats, including plain text, HTML, and JSON. Pantheon supported the initial development and Four Kitchens was responsible for the development of site audit from 2014 to 2016.

Blazy module provides lazy image loading to save bandwidth and avoid a higher bounce rate. This allows you to reduce loading time as it will not load a large number of images that are not visible and save data usage if the users don't browse the whole page. This Drupal performance module is mobile friendly and doesn't let images, especially iframes, kill mobile device traffics. The Drupal 9 module also allows you to set the offset to determine how early an image will be visible to your user.

3. Advanced CSS/JS Aggregation
The Advanced CSS/ Aggregation module packed with many submodules allows you to boost the front-end performance of your Drupal website. It will help your website load faster and reduce the number of HTTP requests. This Drupal 9 performance module also supports file comparison techniques like brotli and gzip. The sub-modules include AdvAgg CDN, AdvAgg CSS/JS validator, AdvAgg External Minifier, and more.
This module creates a WebP copy of image style derivatives to decrease loading times. Whenever an image style derivative is created this module will also create a WebP copy of the derivative to be served to supporting browsers. Duo, Pantheon and Acquia are the organizations supporting this Drupal performance module.

Documentation: The most complete and up to date documentation is included with the module, in the README.txt file.
Tome is a static site generator, and a static storage system for content. With this Drupal performance module you can use Drupal in the same way you would use other static site generators like Jekyll or Hugo where everything lives in one repository, and Drupal only runs on your local machine. You can store content in Git and only use Drupal when you need it. With this module static builds are always partial and cached by default and all commands scale using a combination of concurrency and batching. It is split up into two-submodules Tome Static and Tome Sync. You can use them individually or together. OPTASY has funded the development of this Drupal 9 module.

This Drupal 9 module provides all the necessary infrastructure to orchestrate your cache warming processes. You can warm the cache of your critical entities right after you deploy to production. Additionally cron will keep them warm for you. It needs other modules to provide @Warmer plugins. Each warmer plugin is in charge of warming a different type of items. You could have a plugin dedicated to the entity cache, another one for the JSON:API normalizations, another one that hits URLs to warm the CDN cache and more. You can schedule cache warming and use Drush to warm your caches as part of the deployment script of your site. Lullabot supports the development and maintenance of this Drupal performance module while IBM supported the initial development.

This Drupal performance module facilitates cleaning external caching systems, reverse proxies and CDNs as content actually changes. This allows external caching layers to keep unchanged content cached infinitely, making content delivery more efficient, resilient and better guarded against traffic spikes. Acquia sponsored corporate time for Niels Van Mourik to build and design the 8.x-3.x version.

9. Progressive Web App
This module uses Service Worker for caching and offline capabilities. Once the Service Worker is active, page loading is faster. It also creates a configurable manifest.json file to make the website installable on supporting mobile devices. Out of the box, the performance module fulfils enough PWA requirements that the "add to home screen" prompt is automatically triggered when a visitor often returns enough to your website. It provides a perfect PWA Lighthouse audit score by default as well. United Nations supported the development for Drupal 7, Moonraft Innovation Labs is supporting the project maintenance and support, Invotra Ltd sponsored the Drupal 7 development of configurable pattern caching and push notifications and Smile supported the Drupal 8 improvements.
10. Permanent Cache Bin
Permanent Cache Bin provides a way to use Drupal cache but still keep it separate from drush cr. This is when you need to cache some values which are not related to Drupal config or data but are coming from external systems and which don't really need to be deleted when clearing Drupal cache. Acquia, QED42 and Axelerant are supporting this performance module.
