If I remember the documentation properly, Reticulum is capable of 40 mbps maximum throughput speed. That's over Ethernet or serial links or high-speed wireless networks such as Wi-Fi.
Over LoRa you get quite bandwidth constrained, but you also have a lot of resiliency.
With that said, you can have high bandwidth, but high latency as well because of needing to hop multiple piers to get to your destination.
Once you make the connection though, you can download at a pretty decent clip if all the nodes in the middle can support that bandwidth transfer.
Edit: I should already mention that there is a way to access HTTP webpages over reticulum. Look up rserver and meshbrowser. The webpage is accessed like http://destinationhash/, similar to http://longtoraddress.onion/. Since reticulum is end-to-end encrypted, there's no need to have HTTPS.
