![]() ![]() ![]() If you use UDP protocol then Bandwidth Test counts IP header+UDP header+UDP data.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 want to test real throughput of a router, you should run bandwidth test through the tested router not from or to it. Bandwidth Test uses a lot of resources.There is no acknowledgment required by UDP this implementation means that the closest approximation of the throughput can be seen. To see the maximum throughput of a link, the packet size should be set for the maximum MTU allowed by the links which is usually 1500 bytes. The UDP tester sends 110% or more packets than currently reported as received on the other side of the link. Therefore this statistic is not as reliable as the UDP statistic when estimating throughput. As acknowledgments are an internal working of TCP, their size and usage of the link are not included in the throughput statistics. Statistics for throughput are calculated using the entire size of the TCP data stream. Please review the TCP protocol for details on its internal speed settings and how to analyze its behavior. ![]() The TCP test uses the standard TCP protocol with acknowledgments and follows the TCP algorithm on how many packets to send according to latency, dropped packets, and other features in the TCP algorithm. Designate another machine as a client and run this command, substituting the IP address of your server machine for the sample one here: iperf -c 192.168.1.The Bandwidth Tester can be used to measure the throughput to another MikroTik router (either wired or wireless) and thereby help to discover network "bottlenecks". This waits for incoming connections from clients. Take note of the IP address so you can use it on the other machine (the one designated as the client). Your local IP address (assuming an IPv4 local network) starts with either 192.168 or 10. Obtain the IP address of the server machine: ip addr show | grep inet.*brd Once it's installed, you need two machines on the same network to use it (both must have iPerf installed). Debian, Raspbian, and Ubuntu users can install it with apt: sudo apt install iperf IPerf is a great way to test your LAN speed (rather than your Internet speed, as the two previous tools do). To get your upload speed, use the -u flag: $ fast -u The command returns your Internet download speed. Its web interface is located at, and it has a command-line interface available through npm: npm install -global fast-cliīoth the website and command-line utility provide the same basic interface: it's a simple-as-possible speed test: $ fast Fastįast is a service provided by Netflix. It's fast and scriptable, so you can run it regularly and save the output to a file or database for a record of your network speed over time. This gives you your download and upload Internet speeds. Hosted by CenturyLink (Cambridge, UK) : 31.566 ms Then run it with the command speedtest: $ speedtest Install it with: sudo apt install speedtest-cli You can use it as a command-line tool or within a Python script. It's implemented in Python, packaged in Apt, and also available with pip. Three open source tools that enable you to check your internet and network speeds at the command line are Speedtest, Fast, and iPerf. Being able to validate your network connection speed puts you in control of your computer. ![]()
