Performance advice (96)

TitleAdviceScore
Avoid using Google Tag Manager (googletagmanager)The page is using Google Tag Manager, this is a performance risk since non-tech users can add JavaScript to your page.0
Inline CSS for faster first render (inlineCss)The page has both inline CSS and CSS requests even though it uses a HTTP/2-ish connection. If you have many users on slow connections, it can be better to only inline the CSS. Run your own tests and check the waterfall graph to see what happens.95
Long cache headers is good (cacheHeadersLong)The page has 7 request(s) that have a shorter cache time than 30 days (but still a cache time).93

The favicon should be small and cacheable (favicon)The favicon size is 14794 bytes. That's quite big, can you make it smaller? 50
  • https://www.k8s.it/media/website/eth0.ico
Don't use private headers on static content (privateAssets)The page has 1 request(s) with private headers. Make sure that the assets really should be private and only used by one user. Otherwise, make it cacheable for everyone.90
