With this I could get 1. I’m using Samba file sharing via Ubuntu Server edition running on OrangePi 3 over the 1Gbps Ethernet (Cat6) to my Windows 10 based PC with a Gigabit connection. Iperf is an open source, cross-platform, command-line throughput testing tool. It varies a lot, file transfer seems to be faster than iperf. $ iperf3 -h. iperf, Netperf at least are entirely broken as they use OS UDPSocet, which does not perform. How fast is the connection? 40Gbps inbound (1Gbps real world), 1Gbps outbound. v) RLC layer on test equipment XCAL-Pu12 packages drive test, unattended benchmarking and an in-building test solution into a compact, lightweight and powerful tool. To perform an iperf test the user must establish both a server (to discard traffic) and a client (to generate traffic). 3ad, 930 to 945 Mbits/sec from machine B to A when using 802. The first test is using a max transmision unit of 1500 bytes (default)): Looking for a end-to-end test set pair for throughput testing. nPerf speed test is compatible with all broadband and mobile connections Jul 04, 2014 · $ sudo iperf -s ----- Server listening on TCP port 5001 TCP window size: 85. The issue atm is why do I need so many sessions or flows to achieve this bandwidth. When used with AirCheck G2 or OneTouch AT, it can act as an iPerf server. TCP¶ iperf version 3 TCP OUT (client): 666 MBits/sec TCP IN (server): 810 MBits/sec iperf version 2. 66MHz, 1Gbps/sec, twisted pair Syskonnect, 32bit-PCI bus slot at 33MHz, 1Gbps/sec, twisted pair Sender & Receiver Features Fermi Test Network Run iperf to send data in one direction between two computer systems We have added instrumentation within Linux packet receiving path Compiling Linux kernel as background system load by running make – nj Again the machines were directly connected at 1Gbps and a quick test with iperf confirmed that they were getting very nearly that in both directions (~960Mbps). Jul 29, 2015 · Typical for ideal GIGABIT WIRED is about 100 MEGABYTES PER SECOND: 0. May 27, 2020 · It is cross-platform. wiscnet. I use iperf over LAN but not really feasible to do in a normal situation since you would need shell access on both servers (at least to do a download and upload test). You can also test your connection speed using software called “iperf” available at speedtest. I do like the web100 NDT Based on iperf measurements, we have the following observations: (i) multi-fold throughput improvements are achieved over the buffer-tuned TCP both for single and most multiple streams; and (ii The Plugable USB 3. Both of these devices will reflect traffic at up to 1Gbps. From their site: iPerf3 is a tool for active measurements of the maximum achievable  iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. If you want to test just the pipe between you and your ISP, many ISPs provide their own speed test servers for this purpose. When testing speed between those servers using iperf, the report indicates: 930 to 945 Mbits/sec when using balance-rr bonding mode. On 1GBps LAN it gave me from 845 to 849 MBits/sec. I say this because of this line in your log: local 192. Small form-factor pluggable, or SFP, devices are hot-swappable interfaces used primarily in network and storage switches. 5 -r -P 10". iperf 1gbps test
