Why do we need Lighthouse at all when Google also offers similar reports in PageSpeed Insights (PSI)? CrUX data is important because it is how web core vitals are measured, which, in turn, are a ranking factor for Google’s search results. The reason for the distinction is that there are different ways to throttle a network for testing.

Now that Google uses page speed as a ranking factor, many organizations have become laser-focused on performance. Last year, Google made two significant changes to their search indexing and ranking algorithms : In March, indexing became based on the mobile version of a page , rather than desktop. What is Google Lighthouse?

At Google I/O 2014 , Lara Swanson and Paul Lewis discussed performance culture. Mobile networks add a tremendous amount of latency. The new devices and fast networks we use are not necessarily what our users are using. We are not our end users. 40% of people abandon a site that takes longer than 2-3 seconds to load.

The other issue is that the data I’m getting back is based on lab simulations where I can add throttling, determine the device that’s used, and the network connection, among other simulated conditions. On that note, it’s worth calling out that there are multiple flavors of network throttling. Real usage data would be better, of course.

As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks. If your average visitor is on a fast cabled or cellular network, they probably won’t benefit from the new protocols all that much. Two-way latency is often called round-trip time (RTT).

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. For example, TCP requires a “ handshake ” to set up a new connection.

Each HTTP request that is required for the page needs to travel over the network and in turn this consumes energy on both the server and client. While this may not seem significant for websites with low traffic, as traffic to the site begins to increase, so does the amount of energy consumed. It’s a win-win all round!
