2019年11月13日 · iperf3 per default just tests the upload speed. But you can perform a simultaneous upload and download by using --bidir on the client side: iperf3 -c 192.168.1.xxx --bidir On some newer Linux distributions, the -d flag is used instead: iperf3 -c 192.168.1.xxx -d This way you can get both results in a single test.

2024年3月11日 · I have a particular device which acts as a "strange" TLS proxy and I want to measure the throughput of it with IPerf3. The device under test is "Peter". It has an API to trigger connection to two TLS servers. It will proxy their payload from one channel to another. I can run on "Alice" IPerf and before it socat as a TLS proxy.

2011年6月16日 · This is what happened to me. The windows version had the newest one (3.1.3) while for arch installing iperf gave me an old 2.0.5. Installing iperf3 on arch gave me the newest version, after which all went well. –

I am new to using iperf but others in my company use it but today it is acting strangely. From the server: iperf3 -s which results in cmd showing: Server listening on 5201. From the client: iperf...

2023年11月7日 · Connect iperf3 to the server via command line: .\iperf3.exe -c 192.168.177.1 The IP naturally corresponds to the IP of the router. Read the results. Both programs can be interchanged - i.e. you can start the server mode (-s) on the client and the client mode (-c [IP of the client]) on the router. And vice versa. iperf3 without any command will ...

2019年9月16日 · 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). My question is how to use random port with a specific range (5300-5400) while using Iperf/iperf3 -c remotehost

2019年10月12日 · During my testing of iperf3, I noticed that the slowest speed it would ever transfer at despite setting a bandwidth limit on the command-line for iperf3 was 655 KB/sec (even if the command-line argument was set like so): iperf3 -c 10.1.106.82 -u -i 1 -n 10485760 -b 250K

2023年5月8日 · iperf3 -c SERVER -u -b 35M -l 5 -t 60 -R --get-server-output --interval 1 -> Only messages about receiving packages out of order I also tested iperf with the TCP protocol - which I hadnt done before because changing all the connection to TCP made things even worse before.

2019年6月11日 · The syntax is a bit different for iperf3. Example 1Mbps udp test: server side: iperf3 --server client side: iperf3 --udp --client <server ip address> --bitrate 1M What I find really interesting is the server-side doesn't start listening on the udp port until it receives the first incoming udp packet. This is weirdly unintuitive.

2016年11月5日 · There isn't a way to do it directly in iperf3. However, you can adjust down the MTU size set on your network interface, and iperf will respect that. So long as you're looking to set your packet-sizes smaller than the actual network MTU, that is.
