Iperf

Iperf is a command-line tool used in the diagnostics of network speed issues. Iperf measures the maximum network throughput a server can handle. It is particularly useful when experiencing network speed issues, as you can use Iperf to determine which server is unable to reach maximum throughput.

  • remove the epel "yum remove -y epel-release"
  • install the epel "yum --enablerepo=extras install -y epel-release"
  • run "yum clean all"
  • run "yum install iperf"
