How to programmatically upload 100 GB files to many Android tablets as quickly as possible?

Question

linux

It is necessary to upload content (video, audio) to a large number of Android devices as quickly as possible. All devices are the same. Now we are trying to use jmtpfs under Ubuntu (+ 4 USB 3.0 controllers), but with it unstable behavior is observed when uploading a large volume (at some point the transfer stops and everything stops). On the stack

[pid  1679] read(10,  <unfinished ...>
[pid  1505] restart_syscall(<... resuming interrupted poll ...> <unfinished ...>
[pid  1498] read(10,  <unfinished ...>
[pid  1452] read(10,  <unfinished ...>
[pid  1450] read(10,  <unfinished ...>

adb can not be used - for some reason it only works with 3 devices at the same time.
