Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. Instead of going to sites like speedtest. How can I do it? I recommend the speedtest-cli tool for this. I created a blog post Measure Internet Connection Speed from the Linux Command Line that goes into detail of downloading, installing and usage of it. Using pip install --user speedtest-cli gets you a version that is probably newer than the one available from your distribution's repositories.
For Ubuntu If you can't be bothered to install iperf , you could precede any command that shifts a known amount of data with the time command and do a sum. More Details. To use it just point to a file in internet that is relatively bigger so that you can get a better estimate of it. Speed test yourself with good servers.
In the case of my link the speed is less than KB so if you have a higher speed, the server will be the bottleneck for you, not your actual speed. The highest speed you will see is the maximum speed that your connection and the server's connection can offer. If your connection is KB and the place where you are downloading is KB, your max connection will be KB because it is the max for the server you are downloading from.
You need to do the test at least 5 times to have a reliable speed check or at least do it for a minute or two. This will help you have a more accurate check. You need to have at least 4 or 5 different testing sources to have a more accurate speed. Never test only from the same site as this can be affected by your distance to it, any problem in the server and the connections to it, etc. Always test from different servers. This is an alternative to wget. The downside of wget is the lack of parallel connections.
To use aria2 we fist need to download it:. In the image, the -x 4 is how many parallel connections we wish to use. The CN parameter in the next line shows how many active parallel connections were permitted to download from that site. In this case CN is 4. But if we tried to have more connections we would get something like this:. We set 8 parallel connections but the site only allowed a maximum of 5 as shown by CN This could be solved by the -j option which tells aria2c the maximum concurrent connections we want Which by default is 5 but if the server has limited this, -j will not work.
Should be quite accurate and you can add more instances to max your bandwidth. I have yet to test the full script but the single line command "timeout 5 wget url" works, and you get a partially downloaded file as a result if 5 secs is not enough to complete the download. It uses nearest test server but can also use one manually specified by the user. Actually, Ookla, the provider of Speedtest released a command-line utility that is measuring your speed against a huge number of servers spread around the world.
You can find instructions on how to install it on this link and you can use it fairly simple by executing:. Both -s and -f are just optional but if you want to automate your measurement they might be useful. In addition, you can find a list of the servers which speedtest is using on this address in the form of an XML file or on this address with a searchable field: link. Simple bash script based on rexis answer. You can put your own links for testing in links array or read them from file.
I wanted something more advanced than speedtest. So I did the thing I normally do and wrote my own solution:. It's a more generic solution that can be consumed by other Speed Of Stream Questions And Answers Pdf applications. I managed to pinpoint an ISP network issue with it that resulted in doubling my SFTP downstream speed, which resulted in increased happiness. Not being able to find anything that answered all these requirements, I wrote my own while avoiding reinventing the wheel wherever possible. The code has been well tested on Ubuntu The output provides the 3 main metrics download, upload, and ping round-trip times for the closest 20 data-centers to you the tester , plus estimated distances and Internet provider names.

The results I'm getting with speedtest-cli are vastly under what I get from speedtest. You should consider the speedtest-cli and www.
I would be surprised if you get significantly different results consistently if they both use the same server. If they aren't using the same server, then you have no basis for comparison. Lastly, my results for both utilities vary by a factor of from run to run.
I suggest you test servers, and perform 3�4 runs for each server and compare tools. See the link in my comment below for my results. Add a comment.

Incorrect decimal placing? Confirming that speedtest-cli is broken. Doesn't show speeds above 1Mbps. Doesn't transfer any info when claiming to do so. This should really be the accepted answer This should be the right answer. Speed test means download AND upload. Especially if you are hosting something on that machine! Show 21 more comments.

It requires a client and server. One Zero One Zero Those of you who don't have a remote server you can connect to, there are publicly available iperf servers: iperf. I get results with iperf that are a 10th of what speedtest gives me. And those are the effective speeds I reach. Well I use wget for it. That little tool tells me nicely what speed I have.
