For me, the Cloudflare speed test is closer to measuring what I experience in real world use. In the end, which tool you use depends on what you're trying to measure. And neither networkQuality nor Cloudflare's speed test measure how a connection behaves with multiple users stressing a connection. Which can come from a single user, or multiple users sharing the same connection. It can impacted by other traffic in the same connection though. In your example, video conferencing indeed does simulataneous upload and download, but it's also low bandwidth (relatively speaking) and doesn't usually come close to saturating a connection. But the real world is seldom high stress (100Mbps+ connections are rarely pushed to the limit, honestly). The 'networkQuality' tool on macOS and other implementations(1) of the 'RPM' algorithm(2) are very good to see how an Internet connection behaves under high stress. What's more reflective of real world use cases is a hot discussion topic. > which is more reflective of real world video conferencing use cases

I suspect this is due to your browser throttling CPU use and timer granularity for background or occluded tabs⁰ reducing the accuracy of the readings, if the code isn't working to mitigate the effect of these throttles on the calculations. > if you hide the tab running their speedtest you get even higher speeds

Of course this may vary depending on line type (FTTC, “up to 67Mbit down n& 17 up”, generally seeing more like 50/12) and location (due to differences in local network conditions and peering between you & the speedtest) to I'm not surprised to hear you see the results quite different to those I experience. I find more accurate than most, going by the throughput I see to/from other resources, particularly for upstream rates (which some, including Cloudflair, seem to significantly under-measure). > I find massively overestimates my speeds.

That's why these tests are useful, and why we need more like them. It could be that Netflix has technical issues, but you'd read about those. If says you have gigabit, Cloudflare says the same, and is giving you 5mbps, your ISP is messing with your bandwidth. As an ISP you want customers to think websites are nice and fast, because if only Netflix is slow, surely the problem lies with Netflix, right? I can't think of a reason why a shitty ISP would throttle Cloudflare, as Cloudflare mostly hosts small files. Of course that's completely illegal in countries with net neutrality laws, but not every country has those. This is abused for 'unlimited data' subscriptions that aren't unlimited when you actually try to consume more data than a standard subscription would allow you to.

Reduce the bandwidth for all Netflix servers to 5mbps and suddenly you're stuck watching at 480p or 720p, even if the connection can handle multiple 4k streams. Netflix and Google (YouTube) are commercial entities that ISPs will intentionally throttle. It's possible that those are affecting your measurements at very high speeds. Netflix's speedtest is mostly reliable for what it's meant to do, which is solve the question of 'my internet is fast but Netflix keeps buffering'.Įdit: another factor to consider is that accurate timing has been disabled in most browsers because of side channel attacks like SPECTRE.

If you're your own ISP you can make it happen, but on the other hand you'll probably also know how to get statistics directly from your network hardware, in which case the numbers are useless but it still becomes a useful way to spike the load.

No way in hell is Netflix going to allow your single home internet connection to somehow pull in a full gigabit of streaming video. Their compensation makes for some hilarious statistics, but when you're downloading more than 200mbps the speedtest doesn't make much sense anyway. In my experience, the WiFi throughput numbers seem spot on. It's hard to guesstimate the exact bandwidth of the data that arrives in your browser because of differences in protocol, MTU, header compression and all that nonsense, especially over technologies like WiFi. Bandwidth includes every bit on the wire and that's why '940mbps' internet is usually just normal gigabit with a bunch of packet headers and intentionally unused transmit space consuming the phantom 60mbps. seemingly tries to compensate for the overhead.
