A website’s load speed is a key factor for its success. It helps the website rank higher on search engine results and better retain visitors.
Several aspects influence the website speed, from the web hosting features to the page size. Thus, running a website performance test is essential to monitor the website’s loading speed and find points to improve.
This article will analyze 10 website performance test tools to check your website speed and potential improvement suggestions.
WebLOAD is an enterprise-grade performance testing tool available in two formats: self-hosted and Software-as-a-Service (Saas).
Its load test is capable of simulating thousands of virtual users. The test will reveal how your website and its components perform under such load and identify any network or server-side issues.
WebLOAD also offers performance and load testing in production environments. This feature helps developers ensure their websites and web applications are capable of handling real-world traffic.
LoadNinja is a comprehensive performance testing tool that provides real-time analysis and diagnosis of your website.
Its accurate metrics and machine-learning assistant quickly identify and isolate performance issues. The test results also provide actionable insights to improve your website performance.

GTmetrix is one of the most popular free website speed testing tools available. Test customization options let you pick test server locations, and the connection throttling feature makes the test adequate to your website conditions.

Google’s PageSpeed Insights website testing tool measures two types of data: field and lab data.
The field data presents the data collected from real-world experience over a period of time. This provides great insights into what visitors experienced on your website.
On the other hand, the lab data comes from a controlled environment. This minimizes how user variables such as internet connection and different server locations affect the test results.
If you are unsure about what to do with the results, PageSpeed Insights gives suggestions for website performance improvements.
WebPage Test is a free performance test tool with great advanced features.
For example, it’s capable of performing a multiple-run test with up to nine runs. This is especially useful if you want to see the caching effect and revisit load time. At the end of the test, it will also provide speed optimization suggestions.
Another unique feature offered by WebPage Test is the visual comparison test. It tests multiple URLs, with three runs for each URL, and gives you a filmstrip view to visually compare how these pages load.
Google Test My Site is a free speed testing tool for mobile websites. It uses Lighthouse to retrieve the website metrics and presents the test results with a personalized report.
The report includes tech-specific suggestions to improve the website performance, along with recommendations to increase conversions.
