Performance Budgeting
Performance Budgeting is a web development methodology that sets quantitative limits on key performance metrics, such as page load time, file size, or number of requests, to ensure optimal user experience. It involves defining measurable thresholds for performance indicators and monitoring them throughout the development process to prevent regressions. This approach helps teams prioritize performance as a core requirement rather than an afterthought.
Developers should use Performance Budgeting when building websites or applications where speed and responsiveness are critical, such as e-commerce sites, media-rich platforms, or mobile-first projects, to reduce bounce rates and improve user engagement. It is particularly valuable in agile or continuous deployment environments to catch performance issues early, ensuring that new features or code changes do not degrade the user experience. This methodology also aids in making data-driven decisions about trade-offs between functionality and performance.
