Lighthouse - the first significant paint is extremely high

I use Lighthousefrom Google to test my PWA for performance and more. However, I always get extreme numbers with First meaningful paint. The last test gave me the results: 14445.7ms. But when I use the site on my own, it never loads for more than 2 seconds? Am I something wrong here?

The beacon makes your browser connection slower to check how your application will work on a slower 3G connection (simulating someone on a slower mobile connection). Therefore, if you simply download your web application to your desktop browser (or even your mobile browser because your connection is likely to outperform a simulated connection), it will be significantly faster than the Lighthouse simulation.

As for the first paint, the first thing I'll start looking for is the PRPL template -

- as well as a deep look at the Lighthouse report, because it actually tells you what you can optimize in your application if your score is not perfect.
