7 ways to reduce server response time of WordPress website - I am sure, you have also used many online tools to check the performance of WordPress websites you manage and then speed up them. However, it did not receive the expected results.


What is less well known: WordPress website optimization includes working in frontend as well as backend including hosting solution to power your website.


Today, I will discuss the role of WordPress hosting provider to speed up WordPress website along with this hosting solution helps reduce server response time.


However, before I begin, I want you to understand the four-step process that leads to displaying websites on screens.


  1. Request : This is a request launched by the browser from the visitor (also known as a client).

  2. Reply : The request is processed with the necessary assets (website files, resources, etc.) processed by the server and then sent back to the visitor's web browser.

  3. Build : The web browser uses this property to start the rendering process for the requested website.

  4. Rendering : Finally, the website is displayed to visitors.

With 4 steps, the second step (Feedback) is completely host dependent. If the server cannot perform this step, the next step will be delayed thus UX for the visitor.


This is quite common in shared hosting where users are promised enough resources and then distributed among every website hosted on the server. As a result, website performance is affected by lack of adequate resources, making it slow. This slow performance also affects SEO, website user experience.


What is the server response time?

Server response time (also known as Time To First Byte) is the time taken by the server to respond to requests from visitors. TTFB refers to the time frame at which a customer submits a request, and the client browser begins displaying the requested website.


There are three components involved in TTFB measures


Send HTTP request


HTTP request triggered when the original user downloaded the website. The server received this request and prepared an appropriate response. Factors such as network speed, distance to the server affect the time it takes for the server to receive a request.


Processing request


When the server receives a request from the browser, it initiates the same process: run the script, fetch the data from the database, and then run the backend.


Response processing


When the entire response component has been created, the server sends it to the end user. This step depends on the website server performance and the speed of the internet connection at the user.


When looking at the results generated by the online performance analysis tool: WebPageTest, you notice TTFB. According to instructions from Google, the website should not have TTFB over 200 ms.


If you run a WordPress website speed test, you will probably come across slow admin-ajax.php documentation in the results. If yes, learn how to fix it!


How to reduce server response time?


Many factors cause slow server response. However, here, I will emphasize the most prominent element is controlled by the website owner.



  1. The distance between the server and the visitor

Let's start with the basics - data distances have to go both ways!


Before finalizing the host server, you should have an idea of ​​who and where the target audience is. Based on this information, you choose the data center closest to the target audience. It ensures that the latency remains minimal because distance data has to move to and from the server less. Therefore, the server response time improves significantly.


If the object you want is global, take advantage of the WordPress CDN provider that keeps a copy of your website assets at the global distribution node. When the user requests the page, it is served from the nearest node, not the original host.



  1. Traffic

As your business grows, traffic spikes more often.


I illustrate this with an example: if you post a special offer on your coffee shop website, the number of visitors to the website increases significantly. As a result, the server began to receive many requests that required immediate responses. When the resource consumption reaches the limit, server response time starts to increase. Finally, when all resources are consumed, the website will go down, your brand will see a decline in sales + reputation.


I would not suggest that you stop offering free coffee. What you do is improve slow server response time by choosing a web server that's optimized for performance, capable of handling increased traffic.

  1. Storage resources

When starting an online business, the first order must be a thorough collection of server resource requests. This will give you an idea of ​​the amount of server resources you need to start the business and predict the future of resource requirements.


If you are unsure of the process, first contact support from the hosting provider and explain the situation you are having. They will present a working solution in case you encounter it. You even try the service before you really invest in it.


Choose a hosting provider that is constantly upgrading your infrastructure, using the latest hardware, software updates such as PHP 7.3 or HTTP / 2 server.


At the relevant note, it is not always the wisest decision with the largest server available. Efficient resource management and applying all best server management and development best practices also helps you improve server response time.



  1. Database

Database is the place to store all necessary information. It must be optimized so that the server can access, manage and update information without any delay. The unclear / giant database takes more time to get the data right so server response time generally increases.


If you want to fix a database problem, try deleting unneeded, outdated data and then rewriting the query to make it smarter and faster.


You also consider using WordPress database optimization tips to improve performance including adjusting database structure and WordPress plugins related to database optimization.



  1. Dynamic with Static

Dynamic content created at the request runtime generated by visitors is often different for each user. For example, if I order a coffee cup, you order a hamburger, the process will remain the same because of the same user interface from the website. However, server responses will vary due to the different nature of the two orders. The server will take two different data sets from the database and then prepare two separate responses. Now expand the example with the famous restaurant, you have a pretty good idea about the server.


Static content is hard-coded in HTML, JS, CSS and website images. This property does not change at different user input, the server provides the same content to every visitor. This is the fastest way to distribute content because it does not consume server resources, server response time increases.


Experts suggest reducing the static content load into the CDN WordPress to reduce load time, consume server resources.



  1. Server software

The server stack has a serious effect on server response time. In general, the stack consists of a combination of servers and buffers combined to provide processing power to the server. Common stack components include Apache, NGINX, MySQL / MariaDB.


Do not forget to update your WordPress, PHP version. Older versions often require server resources, not efficient at handling responses. WordPress Core Team recommends using PHP7 because of its optimized processing.



  1. Choose WordPress Hosting wisely
