How to improve WordPress website performance and speed?

Are you unhappy with the loading of your WordPress website? Assuming this is the case, at that point you should consider implementing the below-mentioned suggestions. The following are some of the basic solutions that can assist you with improving execution and speed:

1. Use of Cache:

The following plugins can show some significant results in the loading of your WordPress website.

2. Implementing CDN:

Cloudflare CDN has its datacentres all over the globe. With Cloudflare CDN, replicas of your website are generated and users can access the content over your website more effectively. Additionally, with Cloudflare CDN you can get a free SSL certificate which helps in building up a secure environment for data transfer.

3. Compress images:

Images usually take a longer time for loading. Compressing the images make them more web-friendly and can load quicker. The following steps are used for optimizing images.

  • Reduce file size
  • Use JPG images
  • Scale images as per the requirement

4. Make asynchronous requests:

Dependent libraries can cause a roadblock while loading a web page. JavaScript and CSS files fall in this category. Loading these files asynchronously helps in improving the DOM loading time.

5. Remove unnecessary code / plugins / requests:

Unwanted code causes increased code compilation. This code may be in the form of plugins, libraries, hidden section, etc. For improved code optimisation, you can follow the below pointers.

  • Deactivate plugins which are not required
  • Remove junk code
  • Reduce the number of requests

In addition to these recommendations, the following can be considered for further improvement.

1. Perform a code audit:

This step involves understanding the code and figuring out a better solution without hampering the end result. Understanding the behaviour of code, loops, functions, etc. are involved under this method of website optimising. The below steps are to be followed for improving the results.

  • Optimize code
  • Calculate time-complexity of loops
  • Optimize Database requests

2. It's not always the code:

Check for server performance by implementing the same website over different servers. A comparison of the server resources, cost and performance are to be considered here. Server optimisation is vital as it leads to downtime and resources overloading.

3. Tune-up the Apache / MySQL configurations:

Apache and MySQL configurations limit the performance of your website. Optimising the php.ini file and conf.ini files create a significant improvement in the overall website performance.

4. Use the latest version of PHP:

Execution of a function is always quicker when you use the latest PHP version.
