But 100MB per page is ridiculous, expect for embedded videos. I'd be waiting two minutes for each page to load.

Also keep in mind that this isn't a traditional Request/Response model. Much (if not all) of a "website" must be downloaded up front via the torrent network, and then run locally. 100MB per request on a traditional site is ridiculous but 100MB for downloading 1 very large web app from the torrent network is not so crazy.

In the top comment by webpage I meant a blog. I wanted to publish my blog on zeroNet, but I can do it only when I remove all images, which misses the point of my blog.

>600 posts with images, thumbnails, comments with avatars =

This is not all on ONE page

>My wordpress blog started in 2010 with images, thumbnails is 5GB, last time I checked in July.

Again, that is the size of your database, not webpage.
