If you’re using your own servers for both the client-server and listening server side. If you have multiple servers with your dedicated server provider, you can run an Iperf test between them. If you don’t have an IP address of a suitable Iperf listening server, please contact our support and we will provide you with one. Using Iperf commands on the client-server (in this case your server), you will run a benchmark test and show the throughput data of all test connections. Both need to have sufficient bandwidth to perform the tests you are after (If you’re performing a 10Gbps speed test, both servers need a 10GE uplink, the listening server should Ideally have a higher bandwidth capacity than the client server – 20Gbps.). Using Iperf you can test the bandwidth speed from the origin server (iperf client-server) to a destination server (iperf listening server).

This is crucial for testing connections of 10Gbps or higher (opposed to a wget command to download a test file that only holds one connection unable to utilize all of the server resources – usually 1Gbps maximum). The big advantage and main reason why we use Iperf is, that it is capable of running multiple test connections between two servers simultaneously.

How to use Iperf to test 10Gbps network bandwidth

Linux OS: Use the command: apt-get install iperf3Ĭent OS: Use the command: yum install iperf3 You need at least two servers to run an Iperf3 test – a source and a destination server. Iperf measures both TCP and UDP bandwidth performance. The tool can effectively measure the maximum server bandwidth of your uplink. Iperf is a point-to-point network tool for active measurements of throughput between two servers in both directions. Iperf tutorial What is Iperf and how to install it? The Iperf3 tutorial will cover installation commands for Linux OS and CentOS. To test network bandwidth, we always recommend a popular network tool called Iperf3.

To run a reliable test on 10Gbps uplink servers, you need to run multiple simultaneous test connections. This can be a connection between multiple data centers or within the same one. With regards, to the misconceptions regarding the speedtest methods mentioned above, we have decided to write a tutorial on how to perform a network test connection between two servers. How to effectively measure 10Gbps bandwidth? Other forms of connection testing such as the wget command also present limitations (single concurrent connections) which render the method ineffective for testing network throughput in high-bandwidth network environments. Given the average internet connection speed in the US is around 19 Mbps, you’ll never be able to test a server with 10Gbps unmetered bandwidth efficiently. Secondly, if you’re downloading a test file placed on your server from your home device, you are always limited by the network speed of your home connection (the speed you subscribed for with your local ISP). The majority of today’s speedtest servers run on a 1Gbps uplink, so it’s physically impossible to measure higher throughput than the uplink capacity. Therefore you should check what uplink ports their end servers have. Limitations of traditional web speedtest servicesįirstly, the speed test providers run tests between your server and the web servers on their side. It will always show you unreliable results.

They are usually hosted on a domain with a user-friendly web interface, however, using the same speed test service for determining the network throughput of your server is a bad idea. To perform such a test with regards to your home bandwidth connection is easily done with many popular third-party tools. It is therefore important to be able to perform a reliable network bandwidth test to determine if you’re getting what you paid for. When selecting a dedicated server provider for your business, one of the key components of the service price is the network bandwidth capacity available with the server plan.
