 Network testing (benchmarking) with iperf

Server:

$ iperf -s 

$ iperf -s -u

Client:

$ iperf -c <server-ip-addr> 

$ iperf -c <server-ip-addr> -u

Bandwidth Measurement Tools

- iperf (NLANR/DAST) --- For bandwidth testing, iPerf3 is preferred over iPerf1 or 2.

- iperf3 (ESnet) --- Note that iperf3 is not backwards compatible with the original iperf.

- nuttcp ---

- netperf (HP) ---

خب! این ابزارها مهم ترین ها هستند. در دنیای سیستم های توکار باید از اینها استفاده کنید!
