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. So what is the implementation of the CDN performance testing steps?

How to do cdn performance testing? A website that opens slowly may make many visitors and users impatient, so many sites will use cdn acceleration service. "Simulation Test" is often used to evaluate the performance of cdn.

Set up a testing environment

When evaluating multiple CDN vendors that may be used by a Web site, each vendor should provide a simulated environment that does not require any changes from the customer. In addition, CDN vendors should provide "test" domain names to simulate production sites as realistically as possible.

Confirmation of test environment

The temporary test domain name should be "completely" matched to the production site. You can click here to check:

The number of objects is the same, and the number of objects under the test domain should be the same as the number of objects contained in the real website.

The total size of the file is the same, and the number of bytes of the test site should be the same as that of the real site. Of course, due to the different compression methods adopted by each manufacturer, the number of bytes can be "slightly smaller" than the real website.

The caching rules are consistent, and the caching rules used by all CDN vendors should be consistent, because there are some vendors that can cache dynamic requests (such as the overall framework for caching html pages).

If one vendor can do this, but others can't, then the fairness of the test is questionable, because those who adopt a more aggressive caching strategy will gain an advantage. So before we officially begin, we must conduct a comprehensive verification of the configuration.

Types of performance test scenarios

When there is no site in the real production stage for evaluation, there is no "real user", no real user, there is no real user data. At this time, we need to take a comprehensive test to measure.

Comprehensive testing can provide a "clean house" type test environment, which is convenient for us to measure performance. But even comprehensive testing is divided into many types, such as backbone network performance testing, last kilometer testing, cellular network testing (also known as mobile network testing) and so on.

Compared with the server backbone network performance test, the last kilometer test can better reflect the real user experience; and if the website or company has a large number of mobile access customers, then the performance test must be carried out under the mobile network. This will also lead to a discussion about the ability and technology of different vendors to accelerate the mobile side.

What performance testing platform is used?

In general, it is recommended to use a third-party test platform that has some business experience and performance in your industry. Do some simple research to see which companies have published performance-related information, indices, or articles in your industry.

Do not use specific testing tools within a vendor, otherwise the test results will have a very obvious bias. A good simulation test platform should have a number of stable national / global test nodes, which had better be consistent with the business focus areas.

The above is an introduction to the methods of cdn performance testing. 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.
