![]() This is already beyond "a common computer user" or "browser plugin" capabilities.īecause of that, I suggest that the easiest way to measure your own server is to 1) rent another virtual server close to the first one, 2) SSH to the temporary server and wget -O /dev/null the large URL that you prepared (or even run iperf3 on both servers now that you can), 3) discard the temporary server. So if you want reliable results, you can only measure servers that you're in control of (so that the you could make the server publish a 1GB file via HTTP at a known URL that the test service could download). ![]() (And although it'd still be technically easy for a "speed test" service to set up its servers to offer a mode where it downloads an external URL into the test server, I kind of suspect that this would expose it to a few legal risks.) 10MB 10MiB Custom file size download To download a file with a custom size enter the size you would like below and click download. ), as most URLs hosting ordinary HTML webpages are tiny in comparison to the server's upload speed – with serving "only" 200 kB, you'd end up measuring the webapp's processing time and network latency more than you'd measure the actual throughput. Each of these values represents the connection's specific qualities. It does so by running multiple consecutive tests that analyze different aspects of your internet connection, namely ping (latency), download speed, and upload speed. This speed test will download randomly generated data to your browser, calculate your download speed and log your speed test results. The same does not apply to "any random public server" (e.g. An internet speed test measures the connection speed and quality of your connected device to the internet. Use Speedtest on all your devices with our free desktop and mobile apps. Possible to calculate the download time with users own download. The number reported represents the 90th percentile of all download measurements and. Download speed is tested by downloading files of various sizes. This is important when downloading large files such as updates for applications or streaming video services. Servers offered by regular "Speed test" tools have one thing in common: they all publish HTTP URLs which consistently serve a large amount of data to the client – large enough that a measurement could be done over at least several seconds (giving time for TCP flow control to settle, etc). Calculate the time it will take to download a file depending on bandwidth / download speed. Download determines how fast your network connection can get data from the test network.
