In essence, it lessens the effort needed to produce a page view and eases the burden on the web server. It’s the best approach to avoid delays caused by WordPress’ reliance on PHP and a database.

Both novice and seasoned WordPress users may utilize it with ease, thanks to its abundance of settings and automated optimization tools.

You don’t need to be a scientist to launch this rocket, in contrast to many other caching plugins.

How to Speed Up Your WordPress Site

“How do you speed up your WordPress site?” is the million-dollar question.

Choose a Proper Web Host

Your WordPress hosting service plays a major role in website performance. What makes a good hosting provider? A good hosting provider, such as FastComet, takes the extra measures to optimize your website for performance and provides good customer support.

There are a few types of hosting on the market:

  • Shared hosting – The server’s resources are shared by a large number of users. Your website can be affected if one of them has a traffic spike. You must use caution.
  • Dedicated hosting – In this model, a hosting company leases a single server to you along with all of its resources. Your server is yours to use any way you like, and it will speed up your loading time.
  • Managed WordPress hosting – You may use those server options to run your WordPress website at its best. Managed WordPress Hosting provides features specifically designed for the CMS, like security settings, automated upgrades, and much more.

FastComet offers Shared Hosting (FastCloud, FastCloud Plus, FastCloud Extra), as well as Virtual Private Servers (VPS) and Dedicated CPU Servers (DS). Furthermore, as we mentioned, we are among WP Rocket’s long-standing web hosting partners.

Implement Performance Optimization Practices

You may implement various recommended performance optimization practices to shorten page loads and speed up your WordPress site.

To start things off, we advise you to check our post regarding speed test tools. You will find all the necessary info when it comes to the best website performance and speed test tools, as well as guidance on how to use them. 

Continue that journey by going through our thorough article on WordPress image optimization, which could turn out much more important than you may think. While you’re at it, make sure that you avoid hosting your own videos.

Another thing on your list should be database optimization tuning. The fact is that many database problems have their roots in the database itself. The majority of visitors only become aware of issues when they notice a slower site because there are several that can only be discovered when a specific use threshold has been met. It’s crucial to eliminate those errors in order to guarantee that your MySQL database performs consistently and at top speed. They are most frequently hidden by a setup trap or a nuance in your site’s workload.

Furthermore, don’t neglect the importance of updates. Make sure to use the latest WordPress version as soon as you can. New WordPress versions typically come with many additions and bug fixes for the good of your website. 

Along with the WordPress version, you should also have a recent version of PHP installed. For some assistance, you may visit our tutorial on how to change your PHP version. Furthermore, you can even set a custom PHP version per directory (not for your entire server).

Last but not least, JavaScript minification tools can also be crucial when it comes to WordPress performance.
