AWS New I/O optimized I4i - Network Bandwidth

Go back to list

We measure local bandwidth between two identical machines in the same datacenter. The tool used here is Iperf 3 with TCP mode and a number of thread equal to CPU.

iperf3 --client $client_ip --interval 30 --parallel $cpu_number --time 60 --format M --json # On client
iperf3 --server --version4 --interval 30 # On server
