Record free CDN acceleration test method:

1. Test the distribution of cdn nodes with test tools to see how many independent IPs are resolved and how each operator in each region resolves them;

2. Test the CDN through access to test the CDN's processing of cache rules in various situations.

1. Node distribution

In fact, you'd better consult the CDN provider. In addition, you should also look at your own needs, such as focusing on overseas? First tier cities or second and third tier cities. Use the domain name you access to the CDN or other domains that use the CDN, and use the test tool to test.

2. Cache mechanism

The hit rate can only be seen specifically. For example, the page, file download, and video cases are different. If you are familiar with the principle of http cache, you can test the CDN through access when the CDN is connected to your source station.
