How to Optimize a WordPress Site for Speed and Performance


There have been multiple discussions around speed and performance of websites, particularly WordPress sites. In this post, you will find my self assessment of speed and performance results from this site. As I began looking at optimizing the content for my blog for Search engine optimization the matter of website speed came up.

The Need For Speed: Optimizing a WordPress site

Why is my site so slow?

This is a common question asked in Web Hosting or WordPress Forums and sites. For writing this post, I ‘slowed’ down my site to explain typical reasons.

Let us break down this question into multiple elements, and try and answer this query. A WordPress site is a sum of many moving parts. These include, but are not limited to:

CDNCachingContent: (particularly)
Server and MemoryNetwork SpeedsPHP and MySql version
Under the hood of a WordPress site

What is this blog made of

I use the Hestia Theme for WordPress, with about 15 plucing including CDN (Gumlet) and Security Ninja. I use Cloudflare for DNS, though not for the CDN or Content Delivery Network or caching. In other words, the server (VPS in my case) has to do the heavy lifting. I use Gridpane for server and WordPress management, whcih uses Nginx by default at the time of writing.

In terms of plugins, I use Gridpane Redis Object Cache and Nginx Helper plugins for server side, and Fast Velocity Minify plugin for WordPress content delivery. I had autooptimizer plugin previously, which I might get back to in a few days’ time.
