Yes, definitely. I mean, you certainly get better bandwidth and latency depending on popularity and geographic diversity of seeders, and there are even youtube-alternative websites that host videos on IPFS. But for something like browsing from one page to the next, where the payload is small and you want <200ms latency, I think just the DHT lookup might already put you above that budget. I'm guessing though, haven't made any measurements.
Who gets <200ms latency anymore when Google analytics and FB pixel tracking scripts take more than that each and most websites have them?
Those scripts are loaded asynchronously; you can start seeing content before they are ready.
In torrent when you download something you also announce yourself as a seeder. In ipfs afaik you have to explicitly pin something in order for your peer to be announced as a provider.
This means that even if your content in ipfs is popular it won’t be fast.
No, everyone with the item is a seeder in ipfs. Pinning means the node won't delete it.
