Top 5 WordPress CDN – Performance comparison

You must have faced a slow website experience once a while in a day. Out of frustration you immediately look for alternative options on the SERPs.

From the website owner’s point of view, it can be a disastrous situation. High bouncing rates can ultimately negatively affect your SEO.

No matter how well you have hosted your website on the fastest dedicated servers, you cannot solely rely on them. Since the Web’s large network with trillions of users accessing millions of websites, it can cause congestion in the network and hence slow down your website.

Fortunately, like every problem, there is a solution for that, and the same applies here too. Behold the power of CDN, or Content Delivery Network.”

What is CDN?

CDN stands for Content Delivery Network, a network of servers distributed across various locations around the globe. These remote servers help deliver web content faster across nodes in the most effective manner, spanning various geographic locations from the origin of the web page to the content delivery server.

Whenever the network encounters a request, it is routed to the closest server, increasing the page load speeds. A CDN minimizes latency issues, resulting in a better experience for the user.

How does CDN work and improve website Performance?

  • As we have already said, a CDN consists of a network of servers located in various geographical locations, which are known as points of presence (PoPs).
  • The main purpose of a CDN is to minimize the physical distance between your website visitors and your website’s origin server.
  • The CDN works by storing the content of your website such as images and stylesheets in the form of a cache and storing them on its edge servers located in various PoPs.
  • When a visitor is trying to access the website or page, the CDN redirects the requests to a server that is nearby to the visitor’s location.
  • For example, a website is hosted in Germany and the visitor is trying to access the website from the USA. In this particular case, the CDN will serve the website pages through the nearest local edge server in the USA.
  • This way it boosts the website loading experience and the user’s request doesn’t have to go through such a long distance to reach the origin server.

What key features you should look into CDN for WordPress?

While selecting a CDN for your WordPress site, there are some key features you need to follow to get optimum performance and compatibility:

1. WordPress Integration: Always look for a CDN that offers easy integration with WordPress. For that, some CDNs have dedicated plugins or inbuilt integration options for WordPress sites which makes it easy and simple to set up.

2. Caching Options: A CDN should also offer various Caching Options such as full page caching, Object caching, object caching, and browser caching specially customized for WordPress sites. These options in the caching mechanism help to boost the website performance and decrease page load times by serving cached content to the users and reducing the origin server load.

3. Global Network of Servers: Prefer to choose only CDN with a large and geographically distributed network of servers. This helps to ensure quick content delivery to users across the globe, reducing latency and boosting the overall website performance.

4. SSL, HTTP/2, and HTTP/3 Support: Check whether the CDN supports SSL as well as the latest HTTP versions such as HTTP/2 and HTTP/3 protocol versions for Fast and secure data transmission between the server and the user’s browser or not. Because SSL is very crucial for protecting sensitive information and building trust.

5. Image Optimization: Images or Graphics used in WordPress websites can have a significant impact on website performance and also place a heavy load on the server. Therefore, many CDNs also offer image optimization features that automatically compress and resize images to reduce file sizes without compromising quality.

6. Analytics and Reporting: Check if the CDN provides you with detailed analytics and reporting tools to monitor website details such as traffic, performance metrics, and CDN usage. With the help of these data, you can optimize your website and find out the areas of improvement.

7. Security Features: A CDN should also offer robust and advanced security features to safeguard your website from various online threats such as DDoS attacks and hacking attempts. Look for features such as Web Application Firewall, DDoS mitigation, bot protection, etc.

8. Scalability: Make sure the CDN also offers scalability options so that when your website traffic grows, It can handle the sudden spike in traffic without impacting performance and stability.

9. Customer Support: Last but not least, do not forget to consider the Customer support provided by the CDN provider. Always choose CDN that offers responsive customer support, comprehensive guides, tutorials, and FAQs.

Why do you need to have CDN integrated with the WordPress site?

  • Improved Website Performance: A CDN helps to distribute your website’s content across multiple servers worldwide, reducing the physical distance between your site’s visitors and its server. This results in faster loading times and improved performance for your WordPress site.
  • Scalability: CDNs are designed to handle large amounts of traffic effectively. By offloading some of the server load to the CDN, your WordPress site can better handle spikes in traffic without experiencing downtime or slowdowns.
  • Global Reach: With servers located in various geographic locations, a CDN ensures that your WordPress site can be accessed quickly from anywhere in the world. This is particularly beneficial if your site has an international audience.
  • Enhanced Security: Some CDNs offer security features such as DDoS protection, web application firewalls, and SSL/TLS encryption. These help to protect your WordPress site from various online threats, ensuring the security and integrity of your content.
  • SEO Benefits: Faster loading times and improved performance resulting from using a CDN can positively impact your WordPress site’s search engine rankings. Search engines like Google consider website speed as a ranking factor, so a faster site can potentially lead to higher visibility in search results.
  • Bandwidth Savings: By caching and serving static content from edge servers, a CDN reduces the bandwidth usage of your WordPress hosting server. This can lead to cost savings, especially if your hosting plan includes bandwidth limitations or if you pay for bandwidth usage.

Pros and Cons of CDN

To get a better idea of How CDN can be beneficial for you and what are its shortcomings, check out their pros and cons.

Pros of CDN

  • Bring down the server load: Due to the strategic placement of the servers across the globe, the size of each request can be taken down by a lot, as the content is spread out on various servers rather than just dumping all the content on one big server.
  • Decreased Latency and packet data loss: As the various servers are spread out and are near the prospective user groups, the time taken to complete each request is reduced.
  • 100% site up time: If one of the servers goes down or encounters any problem, this will not lead to the site going down and becoming unavailable. The network would sense this and point the request to the next closest server.
  • Increased Concurrent Users: Strategical placement of servers can provide a high network backbone capacity, which could mean a higher number of users that can concurrently access the network.

Cons of CDN

  •  Cost: The biggest drawback of CDN is undoubtedly the price factor. A CDN has high setup fees along with other hidden charges, which make it very difficult for a small company to make use of it.
  • Impractical: The concept of CDn itself is a very complex one by nature and hence it is very difficult to set up and get to work properly for all users all across the globe.m Also the maintenance of such a network can be extremely difficult and might require a small team on itself.
  • No Direct Control: If any changes are to be made to the site, it has to be made through the CDN provider and can not be made directly. This could cause problems for editors and developers.

Top 5 CDN providers (Running Tests and Comparison)

We are using a WordPress 6.4 website, with around 200 posts and 200 attachments. The WordPress site is running on a Nginx server with PHP 8.1.

A. Test 1: WebpageSpeed Test

In this test, the same site will run on the web page performance test on The site will be tested from 4 different locations across the globe and the time from all the locations and the average Load time for all locations will be compared. Another parameter in which we are interested is the ‘First Byte‘ time. The site is hosted on a server in Dallas, Texas. This test will be conducted from 4 locations :

  • San Jose
  • New York
  • Amsterdam
  • Sydney

A.1. Load Time & Time to first byte (San Jose)

A.5. Overall Average Load Time & TTFB of all locations

Since the server on which our test site is hosted, is located in Dallas, we see there isn’t much difference in the Load times between CDN-enabled and non-CDN-enabled tests, but as we test from different continents we see this gap increase a lot. This stress on one of the main benefits of a CDN.

The results clearly show that CloudFlare, CDN77, and Amazon CloudFront have performed better than the other services in terms of load time.

B. Test 2: Load Test

The second test is an application load test on This will test the site for 10 concurrent users sending requests to the site over 10 minutes. From this test, we will look into the ‘Requests per second‘ and the ‘Response time‘ parameters for each CDN.

B.1. Requests Per Second

Top WordPress CDN Avg requsets per second

We can see that the CDNs perform much better than the sites running without CDNs. All the CDNs performed almost similarly in this test with Amazon CloudFront having just a slight edge.

B.2. Average Response Time

Top WordPress CDN Avg Response time
Top WordPress CDN Avg Response time

The Average response time result may look surprising but it shows a high value for the CDNs because almost all the CDN providers gave a very high Peak Response time value. This was right at the start of the test, but once that stabilized, the response times were less than those of the site running without CDN.

Again in this test, we see that CloudFlare and Amazon Cloudfront did better than the other services.

Conclusion – Top WordPress CDN

In both tests, you can see that the numbers tell the truth, with almost all CDNs performing equally well. However, Cloudflare and Amazon CloudFront performed slightly better than the others. Additionally, Cloudflare is extremely popular, with many web hosting companies offering this service for free in their web hosting plans.

Even WPOven is not behind; it is also a proud partner of Cloudflare and offers free Cloudflare service with every plan.

Now you will be able to choose the right one, won’t you?

  1. Hey,

    But if you move the EXISTING pictures from WordPress to a new external CDN, do you then know of an easy way to migrate all the existing links that are already posted all over the blog? Even more, some of those services will create internal paths and file names, so there’s no way to map existing pictures in WordPress with the same file in the new location…

    Or can you think of a way to achieve this migration?
