How do I check my iPerf bandwidth?

Article Content

1. Download the iperf utility.
2. On the server that will be receiving data, open an elevated command window and run the following command: “iperf.exe –s –w 2m”.
3. On the server that will be sending data, open an elevated command window and run the following command: “iperf –c x.x.x.x –w 2m –t 30s –i 1s”.

How do I test my maximum bandwidth?

The Maximum bandwidth can be calculated as follows: where RWIN is the TCP Receive Window and RTT is the round-trip time for the path. The Max TCP Window size in the absence of TCP window scale option is 65,535 bytes. Example: Max Bandwidth = 65,535 bytes / 0.220 s = 297886.36 B/s * 8 = 2.383 Mbit/s.

What is iPerf and how do you use it?

Iperf is a commonly used network testing tool that can create TCP and UDP data streams and measure the throughput of a network that is carrying them. Iperf allows the user to set various parameters that can be used for testing a network, or alternatively for optimizing or tuning a network.

How do I check my uplink bandwidth?

Try to download a test file within the serverius network. For instance: http://speedtest.serverius.net/files/2000mb.bin If this gives a good result, you will know its not your server or switch or uplink.

How do I test network bandwidth between two computers?

Testing the speed between two computers on a local network can be done by copying a large file from one computer to the second. The speed will vary depending on the performance of the computer’s and medium used to transmit data. For example, an Ethernet cable may be faster than a wireless transfer.

What should my bandwidth be?

Recommendations: For social media, email or light video streaming: 10-25 Mbps download bandwidth. For gaming or heavy use of video, especially 4K: 50-100 Mbps download bandwidth. For most households: At least 3 Mbps upload bandwidth, or at least 10% of your download bandwidth.

How reliable is iperf?

In most cases the results reported by Iperf are close to the real available bandwidth, however the results of the test can’t always be taken at face value: TCP throughput is not available bandwidth: Iperf returns the rate at which data is reliably transferred from C to S over a single TCP connection (by default).

Is iperf a TCP or UDP?

By default iPerf uses TCP/UDP port 5201/5001 (depending on version) for ports during transfer.
