Compress all the models into one single ByteArray chunk and send it to the Client. Then use "ByteArray.deflate" to uncompress that data? Or send it as zip compressed stream and use nochumps zip classes to extract the models.
The most important thing is, to minimize requests. The most flexible solution would probably be: - Client sends a request that contains the needed models to the server - Server component searches for the requested models (in DB or files) and packs them into a compressed format - Server component sends back the compressed data as a chunk of bytes. - Client unpacks the bytestream and can then access the model data. Should't be a big deal to do something like this. And will probably speed up thing significantly when dealing with lots of models. For extra speed, also implement a caching mechanism...
