We have chosen to only evaluate target data when it is needed. Otherwise, the transfer of data is wasted CPU cycles. Call it inefficient if you will, but it's still way more efficient to transfer 24 bytes of data only two to three times in autonomous, then it is to continuously use processor cycles to process a stream.

You can keep an established TCP connection open without sending data, and only send data on request. This allows one to avoid the overhead of establishing and tearing down a TCP connection for every request, and is a common optimization in network protocol design.
