Hi, I'm currently doing my undergraduate thesis where I compare Protocol Buffers and Flatbuffers as serialization formats for raw OSM data in map-based Web GIS applications. The client makes a request to the server who respond with OSM data. My question is, what are the typical data sizes (KB or MB) for this kind of architecture? Is there any max/min size of what is typically sent? I imagine you wouldnt send the whole Planet.osm to the client. Is there a way for me to generate these test files given a max and min size? Any answers who point me in the right direction is very appreciated. I feel like im overwhelmed with information and cant seem to find an article discussing this.

The OSM (editing) API currently returns data in the standard OSM XML representation and limits responses both in geographic extent and size, see https://wiki.openstreetmap.org/wiki/API_v0.6 capabilities and map endpoint.

If you simply want to retrieve the same area in multiple formats https://extract.bbbike.org/ is something you should look at. http://download.geofabrik.de/ has downloads in pbf format for individual countries.
