Andreas, when changing the datarate from 2Mbps to 1bps and sending say a
100 byte packet, you  are increasing the transmission delay from about
400 usec to 800 seconds.  The packet is experiencing a large delay and
you have to wait for a while (a long while) for the packet to get
through before the next packet is processed.

When you toggle the rate without sending a packet, you don't see this
behavior because no packet was sent with the 1bps rate.
