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.

Alibaba Cloud Dynamic Route for CDN (DCDN) provides the following optimization features.
Feature Description
Configure HTML optimization This feature enables DCDN 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, DCDN automatically compresses text files into Gzip files. This reduces file sizes, accelerates content delivery, and reduces bandwidth usage.
Configure Brotli compression This feature allows DCDN nodes to use Brotli to compress text files before the files are returned to users. This reduces file sizes, accelerates content delivery, and reduces bandwidth usage.
Configure image editing This feature allows you to edit and distribute images on DCDN nodes. This relieves the pressure on the origin server, simplifies the back-to-origin routing process, and reduces the amount of network traffic generated during the back-to-origin process.
Configure parameter filtering If a request URL contains a question mark (?) followed by parameters, this feature determines whether to redirect the URL that contains parameters to the origin server.
Configure video seeking This feature allows you to seek through video or audio without affecting the playback quality.
