- Step 2: Update Your System.
- Step 3: Install iperf in Linux.
- Step 4: Check iperf version.
- Step 5: Perform Network throughput Test.
How use iperf Linux?
Iperf is an open source networking tool used to measure throughput or performance of a network. It can be used to test TCP and UDP. Iperf can be used in Windows, Linux, and MAC etc operation system….Important Iperf Arguments:
| Argument | Meaning |
|---|---|
| -V | Used when IPv6 address is used instead of IPv4 |
What is the difference between iperf and iperf3?
iperf is a simple tool to let you measure memory-to-memory performance access a network. iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 is not backwards compatible with iperf2. x.
What is option in iperf?
The basics of using iperf are simple. Install it on a server and a client, then run iperf -s on the server and iperf -c on the client. The -s option signifies server, whilst the -c option indicates client. The -i option defines the interval in seconds that iperf reports the metrics.
What port does iperf use?
port 5201/5001
By default iPerf uses TCP/UDP port 5201/5001 (depending on version) for ports during transfer. This does not work too well for ECMP testing. Specifying the -P flag tells iPerf to spawn multiple client threads, where the source port uses 5201 as well as a series of ephemeral ports.
What is iperf command in Linux?
iPerf is an open source, free, network performance measurement tool. It works by simply sending traffic from one host to another and measuring the bandwidth that can be achieved. In addition to the throughput measurement it can give metrics such as packet loss, jitter, and traffic distribution.

Is iPerf a TCP or UDP?
Iperf supports two types of transport protocols: TCP and UDP. The major differences between the TCP and the UDP test are bandwidth and results returned. In TCP mode the sender generates as much data as supported by the network, while in UDP mode the user has to define the rate of transmission.
Does Iperf write to disk?
The latest version of iperf3 now supports disk to disk testing. Note that for disk write tests, you need to run a longer test to factor out network buffering issues.
