TCP Performance

On EVM QNX prompt:

iperf2 -s

Host PC commands::

iperf -c <evm_ip> -r

iperf -c <evm_ip> -d

UDP Performance

On EVM QNX prompt:

iperf2 -u -s

Host PC commands::

• Test with datagram length of 256B::

iperf -c <evm_ip> -u -l256 -b<bw> -r

where <bw> is 25M, 50M, 100M, etc

• Test with datagram length of 512B::

iperf -c <evm_ip> -u -l512 -b<bw> -r

where <bw> is 25M, 50M, 100M, etc

• Test with datagram length of 1470B (max)::

iperf -c <evm_ip> -u -b<bw> -r

where <bw> is 25M, 50M, 100M, etc
