How to perform network throughput tests with iperf Iperf is a command line-only tool that is used to diagnose network speed issues. Iperf measures the maximum network throughput a server can handle and reports the results back to you. Linux每天一个命令：iperf - chengd - 博客园 2017-9-22 · Iperf在指定的时间内，重复的发送指定长度的数据包。默认是10秒钟。 Summary Results: [ ID] Interval Transfer Bandwidth Jitter Lost / Total Datagrams [ 5] 0.00-2.05 sec 0.00 Bytes iPerf - The TCP, UDP and SCTP network bandwidth What is iPerf / iPerf3 ? iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). networking - How do I interpret iperf3 results? - Unix
The results? By default, data is sent from the client to the server (unless -R is specified, in which case this is reversed). So if this is a result of a unidirectional transfer, why are there 2 lines in the result? The ID values. They are all 4 in my case. When doing a reverse transfer: iperf3 -c IP_ADDRESS -R. the results include one extra field:
Iperf is much more reliable in its test results compared to many other online network speed test providers. An added advantage of using IPERF for testing network performance is the fact that, it is very reliable if you have two servers, both in geographically different locations, and you want to measure network performance between them. Jan 26, 2013 · Ran iperf and noted the 200 plus Mbits, then I copied a 3 gb file from the server to my desktop. Ran iperf again and what I'm calling the return speed (correct me if I'm wrong) is dismal at 13.4 Mbits. The way I interpret the results, good speed to the server, poor speed back from it. Main question. Am I misinterpreting the results? Oct 08, 2019 · Iperf is a command line-only tool that is used to diagnose network speed issues. Iperf measures the maximum network throughput a server can handle and reports the results back to you. If you start iperf client in reverse mode, iperf server will send data and iperf client will receive. In such case results we got during the test: [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 569 MBytes 478 Mbits/sec sender [ 4] 0.00-10.00 sec 569 MBytes 478 Mbits/sec receiver
-w: by default the iperf tool uses a 85KB TCP window size, -w 4M uses a 4MB TCP window size that gives more realistic results,-f: by default the iperf tool displays results in Mbits/sec, -f M changes that to MBytes/sec,-t: by default the iperf tool uses 10-second duration period, -t 60 changes that to 60-second duration period.

Important: From the benchmark results, as shown in the above screenshot, there is a variation in values from the server and client.But, you should always consider using the results obtained from the iperf client machine in every test you carry out..
