The speeds recorded vary considerably from one test to the next, and are not remotely reliable or accurate. Furthermore, the test takes a long time to run on mobile devices.
Speedtest.net is probably the most well-known speed test. It's fast, free, and has available to it a huge list of worldwide test locations, making for more accurate results than average.
Speedtest provides an accurate, consistent test experience that consumers trust across the many device types available on today's market.
Considering how well the company is popular and supports more platforms, Speedtest tests can be regarded as a wee bit more reliable than that of Fast. Also, Fast comes across as less transparent about how it conducts the speed tests and its server locations.
Fast.com is the official Netflix speed test website that you can use to test your internet speed to see if your connection is fast enough to stream Netflix.
The throttling occurs when the Netflix app runs or the Netflix servers are accessed, regardless of use. It all depends on the ISP's throttling capabilities. Most mobile internet providers throttle based on app and server.
Netflix recommends a 3 Mbps connection for one standard-quality stream and 5 Mbps for a high-definition stream. Two simultaneous HD quality streams would need around 10 Mbps, and so on. Online video games don't require much bandwidth to play.
But why is Netflix launching Fast.com, when there are other free speed-testing sites online like Ookla's Speedtest.net? Short answer: Netflix believes advertising is antithetical to its brand. “We want our members to have a simple, quick, commercial-free way to estimate the speed their ISP is providing,” Netflix says.
50 Mbps—Good for 2–4 people and 5–7 devices. A speed of 50 Mbps can handle 2–3 video streams plus some extra online activity. 100 Mbps—Good for 4–6 people and up to 10 devices. Most families would be amply covered with a 100 Mbps internet connection.
For most households with three or four people living together, a 300 Mbps internet download is enough for the various uses ranging from online gaming, streaming, and general browsing. According to the Tech21Centry website, 300 Mbps can download a 5-Gigabyte movie file in only 2.2 minutes.
Many experts claim HTML5-based speed tests are more accurate than tests that use Java and Adobe Flash. Others point out that multithread tests such as those used by Ookla (Speedtest.net and branded by many ISPs) don't represent real-world network traffic as well as single-thread tests.
However, many experts have found that speed tests are too often inaccurate. According to Lifewire, these inaccuracies are usually caused by an overlooked detail, like a poorly placed router or a full browser cache.
To see MBps, take the Mbps, and divide by eight or multiply by 0.125. People can find out roughly how long a large file will take to download if they take its size in megabytes, multiply by eight and then divide by their internet speed in Mbps. Mbps is usually used to show the maximum possible speed of a network.
How accurate are they? Sadly, they're often not at all accurate. Sometimes, an internet speed test isn't accurate because the method the service uses isn't great, but often it's because of an overlooked detail.
The FCC says the best ISPs for two or more connected devices and moderate to heavy internet use should offer at least 12 megabits per second (Mbps) of download speed. For four or more devices, 25 Mbps is recommended.
Speedtest is measuring your real-time network connection, so tests taken within a few minutes of each other might vary a little based on network congestion and available bandwidth. If your Speedtest results are significantly different, make sure that you're: Testing the same connection.
If you want a better Netflix viewing experience, get an internet plan with download speeds of at least 25 Mbps and a generous (2 TB) or unlimited data cap. You'll avoid buffering for the most part and be able to surf the internet at the same time.
Generally quick enough to stream a 1080p (high-def) video. 10-20 mbps: More appropriate for a "super user" who wants a reliable experience to stream content and/or make fast downloads.
We recommend an internet plan with at least 50 Mbps download speeds if you enjoy streaming Netflix. This ensures that your connected devices and one other person can get online and not flip a table over maddeningly slow internet speeds while you watch Schitt's Creek.
15-25 Mbps for streaming HD video. 40-100 Mbps for streaming 4K video and playing online games. 200+ Mbps for streaming 4K video, playing online games, and downloading large files.
What are fast internet upload speeds? Upload speeds of 10 Mbps or higher are generally considered fast internet speeds for upload because they can easily handle the common activities of the average user.
5 Mbps internet provides download speeds at 5 megabits/second and upload speeds up to 0.5 megabits/second. This speed is ideal for businesses with 1–2 employees, as more traffic may slow the connection down. At this rate, a 10 MB file would take approximately 16 seconds to download.
This means you'll use around 2 GB to stream a two-hour SD movie, 6 GB to stream the HD version or 14 GB for the 4K stream. A half-hour TV show would be 500 MB for the SD version, 1.5 GB for the HD version or 3.5 GB for 4K.
Streaming TV and movies in SD, HD or 4K UHD. For standard definition (SD) streaming you'll need at least an average speed of 3Mbps, for HD 5-8Mbps and for 4K UHD you'll need 25Mbps minimum, but we recommend a connection of 50Mbps to cover all scenarios (live 4K broadcasts require more speed, for example).
