# Tag performance

**Tag performance** refers to the impact of the AB Tasty JavaScript tag on your website’s speed, user experience, and technical metrics (like page load time, Core Web Vitals, etc.). The tag is responsible for loading and executing experiments, personalizations, and tracking events on your site.

You will find [a performance center inside the AB Tasty platform](https://app2.abtasty.com/settings/performance-center/guidelines): it's useful to understand your tag's weight and find ways to improve it (custom recommendations regarding your specific activities).

For more information about the performance center and guidelines, please refer to the following articles:
