We have a performance dashboard available in one of our Grafana instances. This dashboard automatically aggregates metric data from every 4 hours. These changes are displayed after a set number of pages are aggregated.

These pages can be found inside text files in the sitespeed-measurement-setup repository called gitlab Any frontend engineer can contribute to this dashboard. They can contribute by adding or removing URLs of pages to the text files. The changes are pushed live on the next scheduled run after the changes are merged into main.

There are 3 recommended high impact metrics (core web vitals) to review on each page:

For these metrics, lower numbers are better as it means that the website is more performant.
