How to setup WordPress CDN
Suffering from slow loading website? Do you want to make your website loading fast? Have you got five minutes? WordPress CDN will help! Here is how:
Have you tried image optimization and resources minification but still facing the slower performing WordPress website? WordPress CDN would be the answer to your issue.
Before diving deeper into utilizing the WordPress CDN we may first need to understand the CDN.
CDN stands for Content Delivery Network. It’s a distributed content delivery system where the static content of your website delivered to your users from nearest delivery servers.
It may sound a bit confusing at first. Let me explore it in detail. Do you know what happens when a user requests for your website?
In order to understand WordPress CDN better, we may need to understand how HTTP request and response works.
When a user requests for your website, your web server receives the request. It looks for the resource you requested. Process the data and other resources and start producing the response.
A standard HTTP response consists of HTML, CSS, and JS data. It’s the requester’s browsers duty to fetch and render the resources provided by the web server. The HTTP server response contains the location from where the client browser needs to fetch the Images, CSS and JS like static resources.
The resources requests made here are sequential in nature, meaning a requested resources needs be found and downloaded before the next resource request can be made.
It’s the characteristic of HTTP 1.1 the HTTP 2.0 which is the up and coming protocol will support the simultaneous resource requests and downloads.
Not all the web servers are configured/upgraded to HTTP 2.0 whereas many of the latest web browsers are now capable of making HTTP 2.0 based calls.
What is WordPress CDN?
In order to understand about the WordPress CDN, we may need to understand about the CDN first.
So now we know that a client browser will have to make as many static resource calls as defined in the website/webpage HTTP response.
Meaning if I’m the user requesting for your website’s home page, and your home page is consist of six images, three CSS files, and five JS files then my web browser will have to make fourteen static resource calls in order to properly render the page.
As we seen earlier, your browser has to wait for a resource to be responded before it can make another resource call.
The speed of loading the resources depends on two things
Server location: It’s by far most important thing. If your server is far from the user requesting the website. It will take longer time for resources to reach.
Server response speed: How fast your server retrieves the files and respond to the request. It depends on the disk IO, memory, processing power, and network bandwidth.
Resource size: It would obviously take longer time for large size resource to be fetched, transferred, and rendered.
A WordPress CDN server would help you address the most crucial first two things. It will help you address the server location and response speed issues.
Technically speaking there is not much you can do with first two points they rather depend on the server you have your website hosted with.
You can address the second point by changing hosting or opting the cloud infrastructure but you can’t really do much about the first point.
How is WordPress CDN helpful?
WordPress CDN service providers have many servers located on various geolocation. It makes the content delivery faster by mapping the nearest server to the requester’s original location.
A standard WordPress CDN service will allow you to upload or migrate your static resources like Image, CSS, JS, and PDF files that you use frequently use on your website.
A WordPress CDN service provider has multiple servers located in various geo locations. Once you add your content to their server, it mirrors the same content to all of its servers.
Now when a visitor request for your website. All the resources request made to the WordPress CDN servers instead of the original server.
The WordPress CDN server identifies the user’s location and routes the resource request to their nearest server based on user’s location.
It improves the response time by mapping the nearest resource server. Additionally, these WordPress CDN servers are cookieless servers which reduce the header and information parsing overhead.
