iperf3

To measure network throughput, run an iperf3 test between a client and a server endpoint. This facilitates network performance testing and accurately identifies bottlenecks by measuring bandwidth capacity between the two machines.

The best way to test network bandwidth for a video streaming service is to measure TCP throughput between your servers and key user locations. This ensures network capacity can handle the expected load and provides a smooth streaming experience.

Yes, you need to install iperf3 on both the client and server machines to accurately test packet loss. Running the tool on both endpoints ensures precise measurement of network performance issues like dropped packets and bandwidth limits.

Yes, you can measure both TCP and UDP bandwidth with a network performance test. This dual-protocol testing accurately diagnoses network capacity issues and identifies specific bottlenecks affecting different types of traffic across the connection.

A network throughput test shows lower bandwidth than expected to help identify performance bottlenecks. Measuring the actual throughput versus expected capacity reveals network limitations, packet loss, or configuration issues between the client and server endpoints.
