	Client	windows server
	iperf3 -c 10.1.4.10 ( default port 5001 )	iperf3 -s
1M of bandwidth	iperf3 -c 10.1.4.10 -b 1m	iperf3 -s
MSS of 100 ( did not work ) TCP maximum segment size (MSS)	iperf3 -c 10.1.4.10 -b 1m -M 100	iperf3 -s
MTU, or ‘Maximum Transmission Unit	The MSS is usually the MTU - 40 bytes for the TCP/IP header. The MSS is 1460 bytes (1500 byte MTU of the IP packet, or 1514 for ETH packet size). The MTU is the largest block of data that can be handled at layer-3 of the OSI model ( IP packet )
