Iperf Network Throughput Testing.
Iperf3 Open-source and cross platform, Client and Server network bandwidth throughput testing tool.
Iperf is network utility tool potentially used to measuring network bandwidth throughput between two systems available over an IP network.Iperf is a small and quick tool, Iperf3.exe is main executable file can be used standalone without the installation package.
Iperf is a simple and easy network tool accomplish the goal of helping administrator’s measuring bandwidth, delay, jitter, data loss including TCP/UDP Performance and network throughput on available bandwidth on network.
Iperf can measure the throughput of a network, Iperf operates in a client and server mode. It’s open source and cross platform supports variety of operating system including Microsoft window, Linus, UNIX, Apple Etc.Iperf is the robust tool to measure wired and wireless networks bandwidth throughput measuring on TCP/UDP.
Quick Ref -:
Iperf provides Bandwidth Check, Network Throughput, Packet loss, download/upload speed test.

Note -:
iPerf3 servers will only allow one iPerf connection at a time. Multiple tests at the same time is not supported. If a test is in progress, the following message is displayed: “iperf3: error – the server is busy running a test. try again later”

How to use Iperf for window
Note -: Iperf is client and server application and need to execute Iperf on both the machine at same time for result.
- Download the Iperf on both source and destination machines.
- Extract the folder on your desire location –: (Example – (C:\ Drive))
- Verify “iperf3.exe” is available on your desired location.
- Open command prompt (cmd)
Iperf server and client Command
>>> iperf3 -s (turn one of the systems in to the Iperf server)
>> > iperf3 -c server_IPaddress (turn one of the systems in to the Iperf client)
>>> iperf3 – ? (Help)
Iperf Demonstration for Bandwidth Throughput Testing -:
Server Machine (IP – 192.168.0.184)
Open server Machine command prompt and follow the below steps
C:\>cd iperf
C:\iperf>iperf3.exe –s
Client Machine
Open Client Machine command prompt and follow the below steps
C:\>cd iperf
C:\iperf>iperf3.exe -c 192.168.0.184 << ————— Server IP

Iperf Descriptions
Server specific
- -s, –server: Starts iPerf in server mode and waits for an iPerf client to contact it.
Client/server
- -u, –udp: Uses UDP instead of TCP.
- -p, –port <Port>: Connects with or expects data packets on this port (default: 5001).
- -B, –bind <Interface>: Permits the connection only via the specified interface (IP address or interface name).
