I´ve got an issue with my pagespeed performance, I cannot resolve.
When I run Lighthouse from the Chrome Dev Tools, the overall performance is quite ok (not perfect, but ok...).
When I run Lighthouse in a separate Tab or when I use pagespeed insights the performance is terrible.
Main difference: Dev Tools and Lighthouse run from within Dev Tools make use of HTTP/2, while Lighthouse in a separate Tab and Pagespeed insights both use HTTP 1.1 and tell me to activate HTTP/2.
Does anyone have an idea, why it works in Dev Tools, but not when it runs separately?
