Self hosted build loading slow - download the whole project before enter

I have tried with self-hosted and found it will download the whole project (around 400mb) before entering the game. I already unchecked ‘Preloaded’ option on most assets and when I run it on PlayCanvas, it’s loading pretty fast (only download the assets related to the default scene (around 20mb).

Can anyone please help me to hosting on own server with less time of loading.

Can you post a link to your self boost build please? There shouldn’t be a difference between the self hosting and our hosted builds
