bw = 7.12 based on packet size = 11Kbits, RTT = 55.10msec, and loss = 7.954183965921402E-4
The theoretical network limit is 7.12 Mbps
The transmit buffer (63.0 KByte) limits the application to 9.07 Mbps
Your receive buffer (63.0 KByte) limits the application to 9.04 Mbps
The network based flow control limits the application to 9.24 Mbps
