With today's mobile-first, search engines such as Google are putting a heavy priority on website loading speed on mobile (and desktop). There is no denying that having a high traffic website that loads fast will be beneficial for you.

When it comes to making a high traffic WordPress sites, there are several factors that you need to focus on such as:

  • Understand what is website loading speed and why it matters
  • Overall website loading speed on mobile

If you are managing several high traffic WordPress sites, you might experience website loading speed slow and being paranoid over it.

Here are some quick fixes to make high traffic WordPress sites load faster.

1. Get a high-performance website hosting solution

High Performance Web Hosting For High Traffic Websites To Improve Loading Speed
~Your web hosting solution plays a critical role in website loading speed

One of the biggest culprits to a slow website loading speed for a high traffic website is the web hosting that you are using. Cheap web hosting especially shared hosting solutions are often not optimized for high traffic.

Since it is a shared hosting solution, you are sharing server resources with hundreds and thousands of other websites. Without a strong server performance, your website loading speed will increase dramatically especially during traffic spikes.

Do I need a high performance hosting for my WordPress site?

If you are constantly serving over 50,000 visits per month or managing an eCommerce store, chances are a shared hosting solution is not going to fit your needs. A better hosting solution such as more server performance and higher PHP worker counts could dramatically improve your website loading speed.


2. Increase the number of PHP workers

PHP workers execute the code on your WordPress site. High traffic websites especially eCommerce stores requires to execute multiple codes at any given time. With a limited number of PHP workers, any high traffic site will experience slow loading speed which will impact the user's experience and your overall website loading speed.

Using a much powerful hosting solution allows you to have additional PHP workers per site to handle multiple requests to execute simultaneously.

As a result, the website loading speed will improve dramatically.

How to determine how many PHP workers I need?

While there are no exact method to determine the number of PHP workers you would need, here are two simple guidelines you can follow.

Examples of this type of website include informational websites or small business websites. The content on these websites doesn’t change much and most responses are cached.

If you have less than 50,000 traffic per month, you don't need more than 2 PHP workers.

Examples of this type of website include eCommerce websites or forum-based websites. These websites typically have a much higher volume of traffic and will be much more demanding with uncached responses. The PHP worker limit for dynamic websites needs to be much higher to ensure speed and performance.

These types of websites usually require more than 2 PHP workers.

What happens if I don’t have enough PHP workers?

Determining the right amount of PHP workers is important to prevent performance issues. When you reach your PHP worker limit, they will start building up in a queue and eventually begin moving out the oldest requests.

The result for users could be the dreaded 504 errors, 502 bad gateway errors or other incomplete requests. Often times there will be slow uncached requests that delay processing, but this problem is solved easily by increasing the number of PHP workers.


3. Integrate with CDN services

Content Delivery Network or CDN is an important strategy to improve website loading speed for high traffic sites.

Using a CDN service, you will be able to serve website visitors with faster delivery load and reducing the wait time.

In layman's term, your website will load faster on the user's end.

For benchmark purposes, your website should load under 2 seconds regardless of the number of website visitors or how heavy your site is.

Don't forget that a faster website will be able to reduce the chance of bounce rate and at the same time, sending the right signals to Google for an improved ranking too!

content delivery network is a system of distributed servers (network) that deliver pages and other web content to a user, based on the geographic locations of the user, the origin of the webpage and the content delivery server.

Which CDN is right for me?

When it comes to CDN services, there are many different CDN services that you can choose from. The most common one is Cloudflare that offers both free and paid plans. Cloudflare paid plans offer superior caching and advanced features that will improve your website loading speed. The free version is sufficient only if you are looking for DNS control and protection from common malware/malicious attacks.


4. Optimize WordPress database

Optimizing your WordPress admin or install is an excellent way to make a high traffic website loads faster. If you are running an aged domain (like over 3 years) or an eCommerce store, your WordPress database would be rather huge.

In this case, you need to perform housekeeping on your WordPress database. Tools such as WP Rocket and Advanced Database Cleaner plugin help you to remove unused content in your database on automation.

Here's how it looks like using WP Rocket to clean your database.

An optimized database also helps you to improve your WordPress backend loading speed while making your frontend loads faster at the same time.

As your WordPress website grows, some of the tables in the database may no longer be in used (especially when you uninstall poorly coded WordPress plugins) and could result in redundancy.

Having a schedule to clean up your WordPress database is a good housekeeping effort to avoid your WordPress taking a long time of load.


5. Optimize images before and after uploading to WordPress

Do you know that a slow website loading speed is always affected by the images on the page?

Images play an important role especially when to website loading speed. But, how do you know if images are dragging your website loading speed?

Performing a website loading speed check will help you determine if images are the main culprit. And if the results show that your images are taking a long time to load, you might need to consider using image CDN and optimizing images before and after uploading to WordPress.

How to use website loading speed check?

There are many speed check that you can use. For us, we tend to use Pingdom Tools most of the time. The results are easy to decipher and understand.

This is how it looks like.

Based on the stats above, the next step is to determine the slowdown and parts of the website that takes the longest to load.

On the Pingdom speed results, here are four parts you need to pay attention to.

  • Content size by content type
  • Requests by content type
  • Content size by domain
  • Requests by domain

Content size by content type. This is the first report that we see. This report allows us to determine the type of content the website has and the exact strategies to take in order for the website to load faster.

Requests by content type. The higher the request count, the higher chances the website will load slower. Reducing the overall requests can improve website loading speed.

Content size by domain. This report is used to understand the waterfall. As the report stated, this is a general report to understand which are the top domains that are serving content on your website.

Requests by domain. Last but not least, this report tells us exactly how many requests are served by a specific domain.
