It's more than a few seconds. On a desktop with a stable fast connection, it takes up to 1GB of RAM and ~17 seconds to finish loading, including around 2.5 seconds of processing time.

On the network side it makes ~650 requests.

That's an exceptionally resource hungry way to load the content.

This varies more than I'd guess by machine. On my Comcast Wifi, it takes 37 seconds to load on my tablet but only 4 seconds to load on my work M3 Macbook Pro with 64 GB of RAM. Maybe Notion developers are issued the latter.
