After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all, you can test whether the CDN acceleration is successful. The following is a brief introduction to some mainstream tools for CDN performance testing.

What are the cdn performance testing tools? Cdn performance testing tool, using a quantitative way to test the performance of the website, such as the first byte loading time or rendering time. Some tools also check specifically to see if resources are cached and whether multiple CSS or JS files are worth merging. Let's introduce it next.

1.WebPagetest

WebPagetest is the gold standard for performance testing, providing a variety of quantitative indicators for performance testing, such as a basic score to evaluate the current level of page optimization, a screenshot showing the visual effect of the loaded page, and a waterfall flow of resources loaded by the browser. By using API wrapper, you can also add WebPagetest-related services to NPM modules and command-line tools.

2.Yslow

Based on Yahoo's high-performance web page dogma, Yslow analyzes the performance of web pages and gives the reasons for slow response.

3.Google PageSpeed

PageSpeed analyzes and optimizes tested web pages based on web page best practices. During the build process, PSI can be used to test the performance of the mobile side and the desktop side, and finally get the test results with good readability.

4.Pingdom website speed test

Enter the URL address to test the page load speed, analyze and identify performance bottlenecks.

5.grunt-perfbudget

The Grunt task used to evaluate performance. Grunt-perfbudget uses public or private instances of WebPagetest to test on a specific URL. It will compare the test results with your expected performance expectations, if it is less than expected, then the task will be completed smoothly, if it exceeds your expected performance expectations, it will report a failure and will help you analyze the reasons for exceeding expectations.

6.Sitespeed

Sitespeed.io is an open source tool based on best practices and some quantitative criteria such as load timing to help developers analyze the loading speed and rendering performance of web pages. It collects data from multiple pages from the developer's site, analyzes them according to rules such as best practices, and outputs the results as HTML or numerically sent to Graphite.

7.speedgun

The site allows you to use Speedgun.js to collect performance data from any public site. It runs five times and displays a friendly diagram to help developers understand the loading process of the current page.

8.SpeedCurve

SpeedCurve allows you to track your competitors' performance as well as your own. When using SpeedCurve, you can see the speed performance of a factor at different sites. For mobile users, they want the website to load faster on the phone than on the computer, and if they feel slow to load, they tend to close the page quickly, so the response speed of the website is very important to them.

9.Calibre

Calibre can help you track the page load time, as well as the page size. Calibre will directly tell you which pages are problematic.

10.GT Metrix

GT Metrix combines Google PageSpeed and YSlow to help developers create a fast, efficient and fully optimized web browsing experience.

The above is an introduction to cdn performance testing tools. The virtual host of the website can enjoy Baidu's massive CDN node resources for free, rich node resources, covering the whole world, and providing acceleration services for a large number of users with unlimited traffic.
