performance budgets

Performance budgets are set limits on how much resources—such as load time, file size, or number of requests—a website or app should use to ensure it runs efficiently and provides a good user experience. Think of it as setting a budget for expenses; by keeping within these limits, developers can prevent the site from becoming slow or bloated, which can frustrate users and harm performance. These budgets help teams prioritize speed and responsiveness during development, promoting optimal performance within predefined parameters to ensure the product works smoothly across devices and network conditions.
