Performance optimization reduces server response time and accelerates file distribution by removing redundant content from web pages, compressing files, editing images, and filtering parameters to increase the cache hit ratio.
For more information about performance indicators, see Performance indicators.
Alibaba Cloud CDN provides the following optimization features.
| Feature | Description |
|---|---|
| Enable HTML optimization | This feature enables Alibaba Cloud CDN to automatically remove redundant content from web pages, such as comments and additional whitespace characters in HTML pages, CSS code, and JavaScript code. This reduces file sizes, accelerates content delivery, and improves website readability. |
| Configure intelligent compression | After you enable the intelligent compression feature, Alibaba Cloud CDN automatically compresses text files into Gzip files. This reduces file sizes, accelerates content delivery, and reduces bandwidth usage. |
| Configure Brotli compression | This feature enables CDN edge nodes to use Brotli to compress text files before the files are returned to users. This reduces the file sizes, accelerates content delivery, and reduces bandwidth usage. |
| Image editing | This feature allows you to edit and distribute images on CDN edge nodes. This simplifies the back-to-origin routing process, reduces the number of requests that are redirected to origin servers, and reduces loads on origin servers. |
| Ignore parameters | After this feature is enabled, the parameters that follow the question mark (?) in request URLs are removed. This increases the cache hit ratio, reduces back-to-origin
requests, and accelerates content delivery. You can specify the parameters that you
want to retain in URLs.
