Server Speedtest mit iperf3


To determine the bandwidth available to the server, EUserv provides servers with special software (iperf3) in the network. With an iperf3 measurement, e.g. errors in your own network configuration or also generally in the network can be detected and limited.

Supported Software:

  • iperf3 (not compatible to iperf)

Supported IP-Protocols:

  • IPv4 and IPv6
  • TCP

Supported Networks:

  • all IPv4 and IPv6 Netblocks of EUserv

Connection of the test stations:

  • 1 Gbit/s


  • External Servers are not supported
  • UDP is not supported for security reasons.
  • Maximum one active connection is supported. If more than one client accesses, you'll receive an error message.

Preparation of the speedtest with iperf3

To prepare a speedtest with iperf3, please proceed as follows:

Install iperf3


 yum -y install epel-release
 yum -y install iperf3

Run the speedtests with iperf3

To run the speedtest with iperf3 for an IPv4-address, please proceed as follows:
