WordPress Stress Test is a method of finding how far you can push your website and where is its breaking point. To Stress Test WordPress you need to test your loading speed, setup quality, plugin performance and more importantly you need to Load Test WordPress.
There are many ways to analyze a WordPress website. You can choose your preferred tool out of hundreds of options out there. You only need to enter your website’s URL in one of these online tools to analyze your website.
You can analyze and improve your website’s performance by running tests. By doing so, you can improve your website and make sure everything is working perfectly fine.
In this article, we talk about WordPress stress test and introduce ways to improve your website’s speed.
The speed of a website is very important to visitors. As we mentioned in previous articles, visitors expect a fully loaded website in less than 2 seconds.
As you can probably tell, this is a hard task to achieve.Although, there are many methods to increase your website’s speed. In addition,there are many ways to analyze your WordPress website.
What is WordPress Stress Test?
Before anything, you need to know what is a WordPress stress test. WordPress stress test or loading test is a method in which you send a certain amount of traffic to a particular website, so you can test how well the system works and how well it can handle the traffic.
A stress test can be done in different environments and scenarios. For example, you want to see how well your website performs during peak hours and how fast it loads. Then you can compare the results with the low-traffic result.
By doing so, you have done a WordPress stress test. Generally, stress test means simulating a huge number of traffic on your website and see how well your website can handle it. As a result, you can prepare yourself for the actual traffic.
Your website may not have Facebook’s daily, weekly or monthly traffic. So, don’t test your website with too much traffic.
The main goal behind the stresstest is to prepare yourself for big traffics on your website. Therefore,simulate a realistic number.
Before You Begin the Stress Test
As mentioned above, the WordPressstress test is done by sending fake visitors to your website. Before runningthe test, remember these points:
- If your hosting plan has a limited bandwidth, you may reach the limit because of the test. Therefore, watch your costs.
- When you run a WordPress stress test, your website may be unavailable for some users. Because your website cannot respond to the high volume of requests.
How to Stress Test WordPress
Now that we’re familiar with the WordPress stress test, let us begin. There are tools that perform the stress test from zero to a hundred and give you a detailed analysis. But they come with a price.
In this article, we explain how to go step by step and perform a free stress test.
1. Test WordPress Loading Speed
The first effective method to test your website performance is to test its loading speed.
The most basic way is to open your website in a new browser and see how long your website takes to fully load.
Although, since this is the most basic way to check your website’s loading speed, you won’t get any crucial information other than the loading time.
If you are looking for more details, we recommend using the Pingdom.
In Pingdom, you enteryour website’s URL then in the “Test from” select a location where most of youractual traffic is coming, or you can select your targeted location.
Finally, click on the StartTest. In a matter of seconds, you get exact and detailed information about yourwebsite’s speed.
2. WordPress Load Testing
Your next task is to test your website’s acceptable traffic. To run this test, we recommend using the Load Impact.
You just need to enter your website’s URL and click on Run free test. This tool simulates 25 users on your website.
The main goal is to see how well your website performs while having high traffic. The test can take up to 5 minutes.
Once it’s done, you are presented with a detailed chart. At first glance, this chart may be hard to read and understand but it’s actually very simple.
The green line is the number of views (written as VUs) Load Impact sent to your site.
As you can see it is increasing gradually to see how the site performs while the views are going up.
The blue line is the time it took your site to respond. You can see a glitch in the chart above, but mostly the site handled viewers well. If the blue line has a sharp slope, you need to look at your site’s performance under pressure.
The violet line is the number of requests sent to the server. Normally it should go up as views are going up. But you can lower the number of requests through means of optimization such as serving resources from a consistent URL.
3. Test Website’s Setup Quality
The next step is to check your website’s installation quality. Like any other web application, WordPress is built with big and small scripts and mechanisms.
It’s the combination of these that makes WordPress the most powerful and popular CMS in the world wide web. GTmetrix is used to check these elements. This tool offers you many ways to test your website.
Just like Pingdom andLoad Impact, you just need to enter your website’s URL and run the test. Aftera while you receive a detailed list of all the tests run on your website:
- Image Optimization
- JavaScript Optimization
- Browser Cache
- CSS Optimization
- HTTP Requests Optimization
- Redirects
- etc.
GTmetrix gives your website a score. For example, if your website doesn’t have good performance and all the points mentioned above aren’t done correctly, you receive the lowest score.
4. Test WordPress Plugin Performance
The last piece of the stress test puzzle is testing your plugin’s performance. To check your plugin’s performance, install Plugin Performance Profiler.
First download the plugin, then install and activate it. Then go to Tools > P3 Plugin Profiler. Click on Start Scan, then Auto Scan to start the process.
After a while, you willsee the results in a chart. This chart tells you how each plugin individuallyimpacts the overall speed of your website.
By using this chart, youcan look for plugins that have slowed down your website. Then replace them withbetter plugins or completely remove them.

How to fix WordPress Performance Issues?
After running WordPress stress test, you need to check the results to see if there are any rooms for improvements. How can you increase your website’s loading speed and performance? Here are some suggestions.
Increase WordPress speed
If your website is too slow, you need to optimize your resources. Below we have listed some common ways of optimizing WordPress.
1. Use CDN
Using CDN is one way to increase your website’s speed. CDN is short for Content Delivery Network.
This system increases your website’s speed. CDN splits requests and sends them to broadcast servers over the network. As a result, the closest server to the user sends the requested information.
2. Optimize WordPress Images
Optimizing your images is another way to increase your website’s speed. Everyone loves high-quality images and every website depends on high-quality images in their content.
On the other hand, they can damage your website’s loading time. The best way to optimize your images is to compress them without losing their quality.
You can use ImageOptim and JPEGmini tools to optimize your images. You also can use the Imagify plugin to optimize your images within the WordPress platform.
3. Install cache plugins
Another way to increase your website’s performance and speed is to use cache plugins. The cache is information stored in the temporary memory. For example, you have hundreds of users on your website. In this case, your website will have a difficult time responding to each of them.
This alone increases your website’s performance and speed. There are many cache plugins in WordPress. However, we recommend W3 Total Cache and WP Super Cache.
Your website may need more time to respond to each request. Now imagine if you are using a cache plugin to display your website to your users. The plugin saves your website from answering repetitive requests. Because all your user needs are saved in the cache.
4. Use GZIP format
Acorn 6 3 3 quart. Another method to increase your website’s performance is using the Gzip feature.
Gzip compresses your files. As a result, your website needs a lesser time to load all the files on your server. Gzip compresses your files before sending them to your server. Then, the browsers unzip them and display them to the user.
You only need to add afew lines of code to your WordPress website to enable Gzip. We have completelyexplained Gzip in another article.

What if WordPress Cannot Handle the Incoming Traffic?
As we mentioned above, byrunning the WordPress stress test you send a lot of fake traffic to yourwebsite. Some servers cannot handle the incoming traffic. Therefore, thisprocess will be unfinished. Remember these points while running the WordPressstress test:
- Use distributor servers like CDN
- Compress your images
- Minimize HTTP requests
- Create a static page of your website. Increase your website’s speed by using cache plugins.
- …
Finding Troublesome Plugins
Plugins are part of every WordPress website. By using plugins, you can add many great features to your WordPress website, without having any programming knowledge or manually doing anything.
Yes, having many pluginscan open a whole new world to you and your website. On the other hand, they canincrease the loading speed of your website.
One method to fix thisissue is to deactivate troublesome plugins or replace them with better plugins.You can do so by using the P3 plugin. We have mentioned this plugin above.
By installing the P3plugin and scanning your installed and activated plugins, you can locate thetroublesome plugins. By using this plugin, you can check which plugins arecausing your website to load slower.
Conclusion
By running WordPress stress test, you can check your website’s performance.
Stress test is mainly concerned with how your site works under pressure. Always optimize your files and codes to have smaller objects to load and fewer requests to make. Although, sometimes the best way is to move to a server with better resources to offer.
The purpose of web server stress testing is to find the target application’s crash point.
The crash point is not always an error message or access violation. It can be a perceptible slowdown in the request processing.
Stress testing can give answers to the following typical questions:
- What load can crash the server application?
- What parameters do we monitor to make sure that the server remains available?
- How do I fail over my web servers and databases?
Creating a Web Server Stress Test
- Record one or more user scenarios.
- (Optional) Modify the recorded traffic.
- Create a load test that will simulate several virtual users.
- Assigns scenarios to the users (you can assign the same scenario to several users orassign an individual scenario to each user).
- Configure the created test:
- Specify the browser, connection speed and start delay for each user.
- Specify the workstation for each user.
- (Optional). Specify service level agreement (SLA) criteria to estimate the performance of the tested web application.
- Run the test.
- Analyze the load test results and check whether the application “crashes”.If the test results contain warnings and errors, this may mean that you have found the crash point.Once again, a crash is not always an error, this may be unacceptable performance.
- If the application did not crash, increase the number of virtual users and perform the test again.
Analyzing Results
During the test run, you can monitor the server parameters on the Runtime > Graphs page in real time. The parameters of primary interest in stress tests are as follows:
- Virtual users
- Passed requests
- Response transfer speed
- Errors
- Warnings
When the server crashes, you may find this out by response transfer speed decrease, or the number of passed requests. In addition, the server may report errors.
As you can see in the image above, the simulation fails when trying to simulate 300 virtual users.
Let's suppose that your application works fine with 10 virtual users, but crashes when working with 300 virtual users. This means that the application crashes at a point between 10 virtual users and 300 virtual users. To get closer to that point, split the user interval into two parts: 10…145 and 145…300, and run the test with 145 virtual users.
If the test with 145 virtual users was not successful, you can then cut the first interval in half and run the test using 77 or 78 virtual users.
If the test with 145 users passes, cut the second interval in half and run the test using 222 or 223 virtual users.
Iflicks 2 2 4 5. Continue splitting the interval until you find the crash point.
Click the image to enlarge it.
Here, we can see that the crash point for the given application occurs at simulation of 220 virtual users.
Reviewing detailed results for the crash point run may clue you up on the server’s instability.
