- A latency limit
- A performance plan
- A speed plan
- A performance budget
Correct answer is: A performance budget
A performance budget is a set of limits on specific metrics that affect site performance. The concept is similar to a financial budget: You set a limit and make sure you stay within it. If you choose to spend a large amount on one thing, you may need to make sacrifices elsewhere to stay within budget. It’s the same give-and-take for user experience and site performance. A performance budget might include the total size of a page, the average page load time, or the size of specific images.
Jude is the product manager for Family.com, a website for genealogists. Earlier this year, many comments from site feedback complained about poor speed. Working with the site marketing and development teams, Jude created a Performance Budget plan where the site speed metrics couldn’t fall below a certain level.
