13 ways to maximize Drupal performance

Drupal Performance

Site speed is crucial when you run a site. If a site takes too much time to load, visitors will get frustrated and leave the site to go elsewhere. Slower performing sites don't rank well on search engines.
Drupal performance optimization can be a complicated specialization in its own right. It takes too long to investigate performance issues and fix them. However, here are some quick fixes and simple methods to move you into the right direction. 
1. Keep the core, contrib module and themes updated
It is critical that you are running the most recent Drupal version as updates by and large contain bug fixes and performance improvements. Keep the core, contribs module, and themes with the latest Drupal update.
To run updates, navigate to “Reports” → “Available Updates.”
You can then click on “Check manually” to scan for additional updates.
2. Enable Page Caching  
To enable, navigate to “Configuration” → “Development” → “Performance.”
Enable “Cache pages for anonymous users” and also “Cache blocks.” You can then choose a time value for minimum cache lifetime and expiration of cached pages.
Click on “Save configuration.”
3. Turn on Block Caching 
Enable caching options for all the blocks that will boost the performance.
4. Aggregate Javascript and CSS files  
Browser doesn’t have to fetch as many files and it reduces the total number of HTTP requests being made. Enhance your frontend performance and download times by aggregating your CSS and Javascript files.
To enable, navigate to “Configuration” → “Development” → “Performance.”
Enable “Aggregate and compress CSS files” and “Aggregate Javascript files.”
Click on “Save configuration.”
5. Disable unnecessary modules
Every module adds to the amount of code that needs to be available for a page load. And it also increases the number of lookups. Wherever possible use a generic module in place of multiple module that does specific functionalities.
6. Cache views content
The views module is probably one of the most popular modules on Drupal 8 development. If you have it installed you can also enable caching on it.
To enable, navigate to “Administration” → “Structure” → “Views.”
Click “Edit” on the view you want to enable caching on.
Expand the “Advanced box.”
Select “Time-based” and click on “Apply (all displays).”
7. Disable DB logging 
When the Database Logging module is enabled, you're shown with a menu item in the "Logging and alerts" of the site configuration. When the Database Logging module is disabled, although the menu item for Database logging goes away, "Logging and Alerts" becomes empty and stays there. If you visit admin/settings/logging, you're shown with an empty page.
8. Reduce 404 Errors
Use third party services such as “online Broken Link Checker” or a tool like Screaming Frog and avoid using a module to check for 404s and save your server’s resources.
Stay away from expensive 404 errors using Drupal Fast 404 module as it can normally such errors with less than 1MB of memory.
9. Fast 404 Responses 
When your site has broken images or CSS file paths, it will reduce the page speed significantly The Fast 404 module changes the way 404 errors are handled, delivering fast 404 error messages.
10. Compress Images 
The loading speed of large image files are slow. Make the file size smaller so they are not larger than they need to be. For image fields, you can use image styles (admin/config/media/image-styles) to resize images to the desired size.
11. Use Sprite Sheets
An image sprite is an aggregation of a single image. A web page loaded with a number of images is slow to load and generates multiple server requests. Reduce multiple server requests with image sprites and save bandwidth.
12. Lazy Loading of Images 
Lazy loading images can substantially increase your page load times by ensuring the image will only load when it is visible to the browser window. “Image Lazyloader” is the most popular Drupal module over 18,000 downloads.
13. Content Delivery Network
Implementing a Content Delivery Network (CDN) with Drupal is a fast and easy way to instantly see decreased load times for your website. Protect your digital assets such as product images, javascript, CSS across the world will ensure that they are delivered faster to your visitors and reducing latency.
This represents a run down of 13 easier ways to boost the performance of Drupal sites. Track the changes to ensure that there is actually an improvement in the performance.
