But I doubt this is mainly a network problem. As a comparison, using syncthing I was able to initially sync (i.e., download to the android device) the complete set of files in about four hours and then checking for changes in the Android takes syncthing about 1 to 3 minutes. I've also repeated this using a private seafile server (seafile server running in the computer); downloading all files takes about the same (about four hours), and then checking for changes against the seafile server takes between 45 minutes and an hour.

So I am wondering if I am making some silly mistake here, or maybe this is not the intended use case (because of number or size of files for an Android device). Of course, computer-to-computer things work just fine. It is the Android part which is not working. |
