PrefaceThe Ali Wireless front-end team has performed a full-scale performance optimization for the business in the past year. The following is a summary of our experience based on the optimization guide, we hope to help.The first section includes only data-load-period optimizations.Picture controlFor Web pages, especially e-commerce pages, pictures usually occupy a lot of visual space, is the most important
good way to optimize. DNS prefetching is the domain name that has this attribute does not need the user clicks the link to parse in the background, but the domain name resolution and the content loading is the serial network operation, therefore this way can reduce the user's wait time, enhances the user experience.

There is a potential for improvement. If we reduce the volume by half, we can reduce the response time by 40%.
It takes less time and resources to improve the frontend than to improve the backend. (To improve the backend, re-design the application planning, code, find methods to optimize the code, add or change hardware configurations, distributed databases, and so on)
Our golden rule is:
