How Does STPTS Internet Speed Test Work?

Internet Speed Test - What Is It?

Internet speed test will show you the connection speed in between you and the connected server to test your internet speed. This Broadband speed test uses a unique algorithm that will show you the exact stable speed you are getting from your ISP. It will find the average of the fastest download/Upload burst rates during your internet speed test from your location to the location of the test server within your web browser itself. Your test results may vary at different times of the day due to network congestion, and the web browser you choose etc. To get a good understanding of your bandwidth bursts averages, run the test at different times of the day from sptps.com. This internet speed test application helps you to determine if there is something wrong with your broadband link. If you are getting too much Ping and very slow download, upload results probably something wrong with your connection or device. If your favorite website is loading slow, you can come here and do an internet speed test and know where is the problem if it's your link or the server where the web site resides

Broadband Speed Checker - How It Works?

Unlike many speed test providers, our test doesn't require Flash and will instead run on any recent web browser with JavaScript, including tablets such as the iPad, Galaxy Tab, Google Nexus or Kindle Fire. You can even test your speed on a mobile phone without installing any apps! We've tested on a range of smartphones include iPhones, Android phones like Samsung Galaxy S4, Moto G and HTC One, and recent Windows Phone devices like the Nokia Lumia 630. If you prefer, our older Flash-based test is also still available.
The test sends a small amount of data to your browser to get a rough idea of how fast your connection is and to measure latency (how quickly transfers begin), based on this figure it then sends a large amount of data and measures how quickly this is transferred. The data transferred is randomised and designed to not benefit from compression and to avoid caching, however it can be affected by proxies and 'turbo' browser features so ensure that these are switched off before you test. We send enough data to saturate your connection ensuring that even the fastest lines are accurately tested. The test is run multiple times and these figures are averaged to get the best indication of your connection's speed. For the upload portion of the test, a similar process occurs but random data is sent back to our servers.
The data our test transfers is not stored on your computer. We use browser cookies to remember your last test result, your postcode and the rating you gave your provider. This is to save you time when you next visit the site, allow comparisons with your last result and to prevent too many duplicate provider ratings. Our cookie only lasts 30 days, but will be rewritten with each test.
Your test results are stored on our servers to allow us to report on the average speeds of each of the providers. This helps other visitors to our site to decide which is the best broadband provider for their needs, as do any ratings you leave for your provider.
Rating your provider or entering your postcode are optional, the test will work without these. However if we have your postcode then we're able to show you the estimated speeds for your line and which technologies are available in your area. This allows you to better understand your speed in context and determine whether you have a fault, or if you're just experiencing the speeds expected in your area.

Download & Upload - Technical Specifications

Technical Specifications of Download Test
  • Our speed test downloads packets of data over an HTTP connection and measures the time the transfers take, in order to work out a download speed in Mbps (Megabits per second).
  • A small initial file is downloaded in order to gauge an approximate speed of the connection. Based on this result, the speed test selects a larger file to perform the main download test.
  • For example, on a slower connection the speed test might choose a payload of 2Mbps, but on a faster connection it may select one of 10Mbps. This enables the speed test to scale and accurately measure all types of connection, from slow ADSL to very fast fibre-optic connections.
  • Additionally, the test simultaneously requests multiple files to download at once. This causes the user's bandwidth to be saturated, providing an accurate picture of their download speed capacity.
  • For this reason, we suggest that users turn off wireless connectivity for any other devices, as well as not running any data-heavy programs at the time of the test, in order to receive the most accurate results for your line's speed.
Technical Specifications of Upload Test
  • Our internet speed test submits packets of data over an HTTP POST connection and times how long the transfers take, in order to work out an upload speed in Mbps.
  • The test submits multiple packets at the same time. This causes the user's bandwidth to be saturated, providing an accurate picture of their upload speed capacity.
What is the Capacity of Speed Test?
  • The speed test has been built to test broadband download speeds up to - and above - 100Mbps.
