Hello
A lot of the variability in your overall Performance score and metric values is not due to Lighthouse. When your Performance score fluctuates it’s usually because of changes in underlying conditions.
Common problems include:
- A/B tests or changes in ads being served
- Internet traffic routing changes
- Testing on different devices, such as a high-performance desktop and a low-performance laptop
- Browser extensions that inject JavaScript and add/modify network requests
- Antivirus software
Lighthouse’s documentation on Variability covers this in more depth.
