We've tidied up our real user monitoring UI, upgraded Chrome and Lighthouse, and published new videos and articles with web performance tips.
Update RUM metric breakdown
The Breakdown tab in our real user monitoring product now shows tables by default, though you can switch to a bar chart via the gear icon.
Lab test recommendation for static resource requests
If you have static files (for example stylesheets, JavaScript code, or images) that get a slow server response, we now highlight those in a custom recommendation and with at request duration badge.
Chrome, Lighthouse, and CPU upgrades
We've upgraded from Chrome 130 to 132 and switched from Lighthouse 12.2 to 12.3.
Tests are also run on new faster CPUs that are consistent across all regions. You might see a change in your page speed on 1 January 2025.

If you want to test your website from different locations, we've launched a free tool toquickly check your Time to First Byte metric from different locations.
You can also check cache hits and server region info if provided by the server.
