You will need to do this on both the client and the server. This is pretty easily done by adding the -p flag. You may run into a situation where you want to run iPerf on a different port. If you lose a frame of a video during transfer, it wouldn’t make much sense to show the frame later on in the movie. UDP is most commonly used for video streaming services. It doesn’t care or check to see if the packets are being received. UDP on the other hand, just sends packets like a crazy person. The TCP protocol checks each time to make sure the target recieved the packets that the origin sent. I’m not a network engineer but I’ll try to explain anyway so someone on internet can tell me I am wrong. See below.Īs you can see, UDP was faster than TCP from the same 2 hosts. On the client side we just need to add the -u flag to start sending UDP packets instead of TCP packets. Continue using iperf3 -s to run the server. When testing with UDP, no changes are required on the server side. You can now walk around your house or office and find all the dead Wifi spots. It shows that I am currently downloading from the server at 135 Mbits/s. This screenshot is from the client running on my iPhone connecting to the iPerf 3 server. On the left you can see the iPerf 3 client is sending data to the iPerf 3 server on the right. Replace that IP address with the IP of the iPerf server. Now we are going to move over to one of our clients. Per iPerf documentation, the default port for iPerf 3 is 5201. It is telling you that the server is listening and on what port. You should see something similar to the snippet above. Clients will be run from mac-mini and my iPhone. It’s no fun troubleshooting the connection on 2 hosts at once.įor all of these demos, some-host will always be running the server. This allows me to only worry about the connection wireless from the client. My server is always connected to my network with a wired connection.

How to Use iPerfĪs mentioned before, iPerf needs to run a client and a server. You still need to have a host on the network running as a server to send data to. I should note that is only useful as a client.

yum install iperf3ĭownload iPerf 3 Wifi Speed Test from the iOS App Store. Run the following command to install iperf3 using yum. Now that we’ve installed Homebrew, we can run the next command to install iperf3 brew install iperf3 You can do this by running the following command. To install iperf3 on your Mac, you’ll want to have homebrew installed. It’s important to note that iPerf3 is not backwards compatible with other versions of iPerf. iPerf3 is currently the newest version of iPerf. We will actually be using iperf3 for this tutorial. How to install iPerf on Mac, CentOS, and iOS This can help you decide if you need to move an access point to another location or even get another access point for the site. If you are setting up a new wireless network for a client or at home, you can do the same to make sure you are happy with your coverage throughout the entire site. Continue this process until you see the connection improve. Every time you move the access point, run another iPerf test with the laptop in the wifi dead zone. You can bring your laptop to the dead zone and move your access point(s) around. Maybe you have a coworker or family member complaining that their wireless internet is too slow. This is helpful if you are trying to troubleshoot wifi dead zones. If I am walking around using my laptop(or phone) wirelessly, I can generate traffic using the client and send it to the hardwired server to see what speeds I am getting. That means it is always running in the background and waiting for a client to connect to it. To do this I keep a hardwired host running in my homelab that runs an iPerf server in Daemon Mode. My favorite use for iPerf is testing wifi. This can be handy if you need to estimate the time it will take for a backup job to run from host to host. One reason was to verify that the connection between 2 hosts was as I expected over a VPN connection. I’ve used iPerf at for a couple of reasons. The server can accept connections from multiple clients on different ports and can even run as a daemon. Tests can run for a set amount of time or using a set amount of data. You can test TCP or UDP throughput using iperf.

Check the download page here to see if your OS is supported. It is available for most operating systems. Iperf is an open source network testing tool used to measure bandwidth from host to host. The best tool I have found for this job is iperf. You probably ended up on this page because you were searching for a way to test your network speed from one host to another.
