The newcomer to the scene was Cumulative Layout Shift (CLS), and, not surprisingly, it's the metric that's gotten the most questions. Does it correlate to user behaviour or business metrics in any measurable way? While I understand why score-based metrics add value, I'm a visual person. It's definitely worth a read.).

Because the average page is now 3MB in size, and this seems like a good time to pause, check our assumptions, and ask ourselves: Is there any reason to care about page size as a performance metric? And if we don't consider page size a meaningful metric, then what should we care about? They represent trends – that's all.

My definition of a performance budget has evolved over the years, but here’s my current working draft: A performance budget is a clearly defined limit on one or more performance metrics that the team agrees not to exceed, and that is used to guide design and development. Meaningful.

One definition of simple, but not a terribly useful one, would be a program that simply memorised input-output examples. Nothing in the authors approach actually tests for this, but the program cost metric used to evaluate generated programs encourages it: a program has lower cost for example, if it is free of conditional branches.

One, by researching on the Internet; Two, by developing small programs and benchmarking. But these are definitely ruled out for enterprise applications due to the complexity in development, maintainability, need for object orientation, and interoperability. The legacy languages — be it ASM or C still rule in terms of performance.

How does page bloat affect other metrics, such as Google's Core Web Vitals? Having said that, looking at data over the past ten years, it's safe to make the observation that pages are definitely trending bigger. These numbers should not be taken as a benchmark for your own site. How does page bloat hurt your business?

A performance budget is a threshold that you apply to the metrics you care about the most. A good performance budget chart, such as the one above, should show you: The metric you're tracking The threshold you've created for that metric When you exceed that threshold How long you stayed out of bounds When you returned to below the threshold 3.

The basic idea of the framework is to use an economic metric such as gross margin as the optimization objective and consider it a function of possible retailer’s actions such as marketing campaigns or assortment adjustments. Moreover, gross margin is not the only performance metric that is important for retailers. Single objective.
