Ever wondered what’s going on behind the scenes of your website? Ever wanted to know how Pressable can make your website so fast? Here are some of the things we’ve implemented which make your WordPress website as zippy as it can be.

Caching

Let’s look at a few definitions:

  1. The modern word “cache” comes from French; it is a derivative of the French verb cacher, to hide.
  2. The French word itself derives from the Latin coācticāre which means “pack together, to press together, to store.”

These definitions give us a pretty good idea of what caching is in terms of the web – it’s the process of packing together and storing content for fast delivery. A web cache is the place where your content is stored.

Every time a visitor lands on your WordPress website, WordPress has to fetch information from your MySQL database. Your visitor is waiting at their computer for WordPress to do this. If you have a lot of functionality and assets on your website, that’s a lot of information to fetch, so your load time increases. When caching is implemented, a static version of the website is stored and served up to visitors. This means that everything is ready to go. You can make changes to your content, and a new version will be stored when the next visitor lands on your website. In terms of performance, caching is one of the most important tools in your armoury.

When your website is hosted by Pressable, we take care of caching for you. You don’t need any plugins or external services, you don’t need to know much about it, just that when your website is hosted on Pressable it’s fast.

Content Delivery Network (CDN)

All of your website’s assets are offloaded to a CDN. All of our customers get to use MaxCDN, a premium CDN provider. A CDN is a distributed network of servers that is used solely for the delivery of assets. Assets include images and graphics, JavaScripts, downloadable files and software. Whenever a visitor lands on your website, the CDN delivers the content from the server that is closest to the visitor. This makes content delivery faster, as well as strengthening your website against surges in traffic. Ever wanted to know how a CDN works? Check out our guide.
