Cache-Headers missing? Lighthouse records metrics from the browser, applies a scoring model to them, and presents an overall performance score. Guidelines for improvement are suggested based on how specific metrics score. During performance tests, Lighthouse records many metrics focused on what a user sees and experiences.

But we can’t really say just yet whether it had any impact on the business metrics — well, we’ll need to wait for a big book release to see that.

One of the costs that Noam mentions is the increased download size, especially JavaScript bundle sizes, that stem from the use of frameworks and other libraries. In particular, the increase in the amount of downloaded JavaScript can have a direct impact on website performance. I highly recommend checking out these articles.

Or worse yet, sometimes I get questions about regaining normal operations after a traffic increase caused performance destabilization. But we can discuss common bottlenecks, how to assess them, and have a better understanding as to why proactive monitoring is so important when it comes to responding to traffic growth.

It increases our visibility and enables us to draw a steady stream of organic (or “free”) traffic to our site. While paid marketing strategies like Google Ads play a part in our approach as well, enhancing our organic traffic remains a major priority. The higher our organic traffic, the more profitable we become as a company.

Often the data is held in memory by consumers and used as a “total cache”, where it is accessed at runtime by client code and atomically swapped out under the hood. for example Open Connect Appliance cache configuration, supported device type IDs, supported payment method metadata, and A/B test configuration.

The scale of the effect can be deeply situational or hard to suss out without solid metrics. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. As networks have improved, client-side CPU time now dominates script download, adding further variability.

As a second example, TCP sees all of the data it transports as a single “file” or byte stream , even if we’re actually using it to transfer several files at the same time (for example, when downloading a web page consisting of many resources). In the early days of the Internet, encrypting traffic was quite costly in terms of processing.

This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed. To be able to download multiple files on a single connection, you need to somehow multiplex them. Prioritization.

This helps support executive sponsors who then have meaningful metrics to point to in justifying the investments being made. Very rarely have we seen a team succeed that doesn’t set budgets, gather RUM metrics, and carry representative customer devices. Teams with budgets also find it easier to track and graph progress.
