Remember the speed testing business is about money - about attracting a lot of testers to get baselines and sell the results - they also show ads on their web - so your data is being collected and the service is not because of your pretty blue eyes - it’s the data you provide them. You could then upload the same file to a server under your control again using time and any upload method supported by your server. You would likely get more accurate result by timing your download using time and curl then calculate the transfer by hand. I wouldn’t go as far as saying lies more like inaccurate which likely describes the results better. In fact when using ookla from the web browser - the calculations is always showing a better speed than my subscription allows for - which makes me think the algorithm for the ookla web test is too generous - but I have no way of knowing for sure. I have noted the differences with speedtest-cli as well - but it is nothing to worry about - it likely due to differences in calculations and you should not put too much trust into them. This is just the scenarios I could pull from memory - there’s likely more.Įven if you are using a browser based test - the browser may influence the test - e.g.browser plugins/add-on. is the test executed connecting directly to the ISP (without local routing).is the test executed through a local router.the method used to calculate the bandwidth.any given activity on the local network.ISP load balance or endpoint load balance. the actual route - which may change between tests - e.g.It is very difficult to identical results as any bandwidth test will be influenced by When calculating the speed of a connection - there’s a lot of factors. It can’t be a coincidence, I tried several times at different timesĪlso I tried “no-install” version of cli: $ curl -s | python. Testing from Turkcell Superonline (**********). I tried rebooting the router, computer and replugging the wifi adapter, but the results are equally bad in the cli versionĬli results: Retrieving configuration. Speedtest.I noticed that speedtest-cli-2.1.3-2 and produce completely different results. has migrated to using pure socket tests instead of HTTP based testsĭifferent versions of Python will execute certain parts of the code faster than othersĬPU and Memory capacity and speed will play a large part in inconsistency between

There are several concepts to be aware of that factor into the potential inconsistency: speedtest-cli is a lightweight, fast, and easy-to-use utility that provides accurate measurements of our internet connection’s upload and download speeds. There is the potential for this tool to report results inconsistent with . In this tutorial, we’ll explore how to use speedtest-cli, a command-line tool, to check internet speed in Linux. It is a relative value used for determining the lowest latency serverįor performing the actual speed test against. Latency reported by this tool should not be relied on as a value indicative of ICMP It is not a goal of this application to be a reliable latency reporting tool. version Show the version number and exit Python API Support systems with insufficient memory, use this Pre allocation isĮnabled by default to improve upload performance. no-pre-allocate Do not pre allocate upload data. secure Use HTTPS instead of HTTP when communicating with timeout TIMEOUT HTTP timeout in seconds. source SOURCE Source IP address to bind to mini MINI URL of the Speedtest Mini server exclude EXCLUDE Exclude a server from selection. server SERVER Specify a server ID to test against. list Display a list of servers sorted by json Suppress verbose output, only show basic information Single character delimiter to use in CSV output. csv Suppress verbose output, only show basic information simple Suppress verbose output, only show basic information share Generate and provide a URL to the share Does notĪffect the image generated by -share, nor output from bytes Display values in bytes instead of bits. single Only use a single connection instead of multiple. no-download Do not perform download test h, -help show this help message and exit Ĭommand line interface for testing internet bandwidth using.
