Loading time Javascript stays the same after implemeting GTM server

Reading this, one of the benefit of GTM server is a faster loading time of the page.

After implementing GTM server by using the tagging server URL from Stape, loading time stays the same.

What have I done wrong because loading should be reduced right?

Hi @Michel_Brok

Are you using our custom loader? That is not evident from the screenshot, you’re downloading it from googletagmanager.com still

Thanks Dan, that helped, JS for GTM is not loaded anymore which is awesome.
