(It's recommend to test both ways and compare your performance. Powerful, properly configured connections have very little variance between the two bandwidth test types.) Test different locales simultaniously. The coast to coast multithread test allows you to test multiple servers simultaneously giving you the most comprehensive results

If I test with the default udp bandwidth using the following command: iperf3 -c xxxxxxxxx.co.uk -u. I get the following output: Connecting to host xxxxxxxxx.co.uk If the only thing you're changing between the TCP bandwidth test and the UDP bandwidth test is the protocol, verify that there are no firewall rules blocking UDP from port 2000 and up. You could try adding a rule explicitly allowing UDP 2000 to 3000, which should be good for a bunch of tests since RouterOS allocates UDP ports as needed. for UDP, bandwidth to send at in bits/sec (default 1 Mbit/sec, implies -u) run in client mode, connecting to "host" Do a bidirectional test simultaneously number of bytes to transmit (instead of -t) Do a bidirectional test individually time in seconds to transmit for (default 10 secs) input the data to be transmitted from a file The syntax is a bit different for iperf3.Example 1Mbps udp test: server side: iperf3 -s client side: iperf3 -u -c client.ip.address -b 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. There is no acknowledgment required by UDP; this implementation means that the closest approximation of the throughput can be seen. Remember that Bandwidth Test uses all available bandwidth (by default) and may impact network usability. If you want to test real throughput of a router, you should run bandwidth test through the router not from or

The iPerf permits to generate TCP and UDP site visitors/load between two hosts. You can use iPerf to shortly measure the utmost community bandwidth (throughput) between a server and a consumer, conduct stress testing of the ISP communication channel, router, community gateway (firewall), your Ethernet or Wi-Fi community.

Jul 22, 2020 · IPerf is an open-source tool designed to test network bandwidth between two network nodes.The iPerf allows to generate TCP and UDP traffic/load between two hosts. You can use iPerf to quickly measure the maximum network bandwidth (throughput) between a server and a client, conduct stress testing of the ISP communication channel, router, network gateway (firewall), your Ethernet or Wi-Fi network. If you want to test real throughput of a router, you should run bandwidth test through the tested router not from or to it. To do this you need at least 3 routers connected in chain: the Bandwidth Server, the router being tested and the Bandwidth Client. If you use UDP protocol then Bandwidth Test counts IP header+UDP header+UDP data.

The user can choose how many tests he/she wants and the time of each test. This software uses the iPerf3 that is a tool for active measurements of the maximum achievable bandwidth on IP networks. Jul 08, 2019 · -u, –udp: Use UDP rather than TCP. See also the -b option.-b, –bandwidth n[KM] Set target bandwidth to n bits/sec (default 1 Mbit/sec for UDP, unlimited for TCP). If there are multiple streams (-P flag), the bandwidth limit is applied separately to each stream. You can also add a ’/’ and a number to the bandwidth specifier. Dec 13, 2019 · Run a 200 Mbps UDP test: iperf3 -c -u -i 1 -b 200M. Note: When testing with UDP, the -b modifier can be used to set a target throughput rate. Use -b 0 for an unlimited bandwidth target. For UDP, without setting this value the throughput values may be very low. Note: Many client/server NIC cards perform TCP checksum/header offloading If you want to test real throughput of a router, you should run bandwidth test through the tested router not from or to it. To do this you need at least 3 routers connected in chain: the Bandwidth Server, the router being tested and the Bandwidth Client.
