"Uncovering the Mystery: Lighthouse's Hidden Performance Concerns

After running a performance test, I encountered an issue.

The recommendation was to run the test in incognito mode, which I did, but the problem persists.

The test is still running and providing a score, but it seems like something is impacting the results.

During this Lighthouse test run, there were issues identified: Stored data in IndexedDB might be affecting loading performance. It is advised to audit this page in an incognito window to eliminate any negative impact on your scores.

Answer №1

To resolve the issue, I was able to eliminate this notification by navigating to the "Application" tab in Inspector and selecting "Clear site data," followed by rerunning the Lighthouse test.

UPDATE: Spoke too soon... initially, it appeared that the problem had been resolved after the first attempt, but upon running the test again a second time, the same warning message reappeared. It's possible that not all data was successfully cleared?

Answer №2

i am encountering the same issue as well:

https://i.sstatic.net/4hqrG.png

Upon checking the site data, I noticed that there is some data in indexdb even though it appears empty when I click on the node for investigation. After clearing the site data, the indexdb content went down to 0 and everything seemed to be cleared. However, the alert message remained unchanged.

Interestingly, when I run Lighthouse in incognito mode, the alert does not appear, indicating that the hint seems to be working correctly on my machine.
