React Nextjs bad performance with almost empty app

Time:01-01

I have created a new Nextjs project and deployed to Vercel.

The project is still almost empty, only one div with few texts on it, But the performance in lighthouse: Time to interactive - TTL and Total blocking time - TBT are already marked as an issue.

What can cause it?

CodePudding user response:

This is quite strange, Lighthouse shows a near-to-perfect score of your website on my computer.

Are you:

  • Using some browser plugins that may affect performance?
  • Having a slower internet connection at times?

I remember having adblockers generating some console errors and warnings on my website for my Google Analytics Tag, that lowered the score until I disabled that plugin on my particular website.
