Logan has been the marketer and site manager for CarFixer.com for the past 10 years. He and the developer team have spent much effort improving the user enjoyment of the site. Recently, performance metrics are showing the speed of the site has regressed significantly over time. Which long-term maintenance program can help by limiting certain metrics that affect performance?

A performance budget is a long-term maintenance program that sets limits on specific metrics affecting website performance, such as page weight, load times, or the number of HTTP requests. By establishing these thresholds and continuously monitoring them, teams can prevent performance regressions over time as new features or content are added. An independent testing program might identify issues but doesn't proactively limit metrics. Automated debuggers help find code errors but aren't designed to manage overall performance metrics long-term. A performance maintenance team is a resource, but a performance budget is the program or methodology they would use to guide their efforts in limiting performance-affecting metrics.
