As a website owner, you want to reduce initial server response time to improve the overall PageSpeed performance of your WordPress website. As the Server Response Time is a critical factor in determining your website’s PageSpeed performance.

Let’s understand the reasons behind the slow server response time and see the top techniques to reduce initial server response time.

What Is Server Response Time? 

Server response time is the span of time it takes for a web server to respond to a request from a browser.

The total time taken to process the browser request, generating the server response, and sending the server response back to the browser is the server response time.

Server Response Time= Time of processing the request + Time of  generating the response + Time of sending it back to the browser.

In simple words, when a user visits your website the browser sends an HTTP request to your web server, asking for your web page’s content such as HTML, CSS stylesheets, JavaScript files, and images for rendering your webpage. 

Therefore, the server processes this HTTP request, generates an HTTP response and sends this response to your user’s browser.

The time takes to complete above processes is called server response time. It is also known as Time to First Byte (TTFB).  

The Benefits Of Reducing Server Response Time

According to Kissmetrics, 47 percent of users expect a website to load its content in less than 2 seconds. Thus, a high server response time would inversely affect user experience.

The Reason Behind Your Slow Server Response Time

It is important to understand the possible reasons behind your slow server response time. Apart from the poor network connection and unreliable hosting, there are many factors that can affect your server response time as well.

Server Response Time
  1. Large-sized images can increase your TTFB value.
  1. Unused CSS stylesheets slow your server response time by increasing the render-blocking resources.
  1. Unoptimized web fonts would slow your web page rendering time.
  1. Using unnecessary characters, such as white space and extra comments, increases the file size. This is one of the reasons behind your slow server response time. 
  1. The geographical distance between the user and the origin server increases the network latency, which also affects the server response time.

10 Techniques To Reduce Initial Server Response Time

If your website’s server response time is high, it will affect website speed performance and user experience. To improve your website’s server response time, you need to implement the strategies below. 

  • Add a Browser Caching Mechanism.
  • Optimize Your All Images.
  • Optimize Your Web Fonts.
  • Reduce Unused CSS
  • Reduce Your Website’s Resource File Size
  • Use a Content Delivery Network 
  • Implement Lazy Loading
  • Compress Your Website’s Assets.
  • Use a Good WordPress Hosting.
  • Avoid Using Too Many Plugins.

Let’s understand these strategies in detail. We will also mention the WordPress plugins that you can use if you are searching for a non-coding solution.

Add a browser caching mechanism

By adding a browser caching mechanism, you can store your WordPress website’s assets in the browser cache, when a user visits your website for the first time.

Therefore, when the user re-visits your website, or load another page on your website this cached content will be rendered faster. By adding a browser caching mechanism, you can reduce the server response time.

If you are technically sound, you can manually add a caching mechanism in your .htaccess file. However, this requires a lot of time and effort.

There are many cache plugins available in your WordPress like RabbitLoader. Using a cache plugin like RabbitLoader on your WordPress website reduce the server response time by adding browser caching along with other optimization techniques. 

Optimize all your images

Images are the most valuable resources on your website. We often add high-resolution images to make the website more attractive. However, unoptimized images increase the server response time by increasing the overall page size. 

Optimizing your large images can easily solve this issue. The best practice is to convert your large JPEG and PNG images into the modern AVIF or WebP format.

By converting the images to the next-gen format ( AVIF or WebP), you can compress the image sizes without compromising their original quality. If you are on WordPress you can use the RabbitLoader plugin for image optimization for your whole website.

Optimize your web fonts

Though web fonts improve your website’s visual appearance, sometimes using unoptimized web fonts harms your website’s PageSpeed performance. A good practice is to use a web-safe font to reduce the server response time.

Web fonts load

However, if you are using fonts that are not web-safe, you should optimize that web-fonts by adding the link preload or fetch priority attribute in your HTML file.

Syntax for adding link preload

<html>

<head>

 <link rel="preload" href="/assets/Pacifico-Bold.woff2" as="font" type="font/woff2" crossorigin>

</head>

</html>

Reduce unused CSS

When you are auditing the PageSpeed performance in Google PSI, you often come across the “eliminate the render-blocking resource” warnings. But what are the render-blocking resources?

CSS stylesheets provide style to a website’s content. Some CSS rules can be defined in CSS stylesheets but not utilized on the website. These rules are known as unused CSS, which can be considered a render-blocking resource.

reduce unused css

Therefore, these unused CSS rules increase your server response time by enlarging your Total Blocking Time (TBT). Reducing this unused CSS can decrease the page size and server response latency.

You can manually delete the unused CSS rule one by one. However, this process would require huge efforts. By using a WordPress plugin like RabbitLoader you can remove all unused CSS without putting any extra effort.

Reduce your HTML, CSS, and JavaScript file size

Developers often use extra characters like white space, unnecessary comments, line breaks, and large variable names to make the code more readable which increases the size of your HTML, stylesheets and scripts and increase the server response time.   

All Resource Optimization

By minifying these website’s resources, you can reduce these file sizes. This would improve your page load time and reduce server response times.

Use a Content Delivery Network 

A high distance between the origin server and the user can increase the server response time by increasing the network latency. Using a Content Delivery Network (CDN) can mitigate this problem by distributing the static content between the proxy/ edge server.

 A Content Delivery Network stores the website’s static and dynamic content on the edge server. When a user requests your website’s content, serving the content from the nearest edge server, CDN would reduce the server response time. 

Implement lazy loading

If you are using too many images on your website, lazy loading is the best solution to optimize your website by improving the performance metrics especially the Largest Contentful Paint (LCP).

lazy loading

Lazy loading allows you to render your above-the-fold images and defer the non-critical resources. In simple words, during your page loading time only the images, present in the visible area are loaded. The remaining images would load when you scroll down to them.

Thus, the page speed of your website will automatically be increased by reducing the initial server response time. 

Compress your website’s assets

Compressing your website’s assets using the GZIP or Brotli methods can reduce server response time. While GZIP is the traditional method, Brotli uses the modern algorithm to compress the website’s resources.

compress your website resources

Using the Brotli algorithm, RabbitLoader compresses all resources of your WordPress website and sends the compressed files over the network. Thus, your server response time would be improved.

Use a Good WordPress Hosting

Using low-cost web hosting might save your costs but harm your website performance by increasing the server response time. In order to reduce this issue, use a dedicated web hosting server.

However, using a dedicated server can be expensive. You can also choose properly optimized shared hosting, which might help reduce your server response time.

Avoid Using Too Many Plugins

In order to optimize your website’s performance, you often use a lot of WordPress plugins. However, using too many optimization plugins would increase the server response time.

avoid too many plugins

You choose the WordPress plugin which has multiple optimization features like RabbitLoader. When you are using RabbitLoader, you don’t need to look for any other optimization tools for adding browser caching, lazy loading, and others.
