What is FAST.com measuring? FAST.com speed test gives you an estimate of your current Internet speed. You will generally be able to get this speed from leading Internet services, which use globally distributed servers.
Why does FAST.com focus primarily on download speed? Download speed is most relevant for people who are consuming content on the Internet, and we want FAST.com to be a very simple and fast speed test.
How are the results calculated? To calculate your Internet speed, FAST.com performs a series of downloads from and uploads to Netflix servers and calculates the maximum speed your Internet connection can provide. More details are in our blog post.
What can I do if I'm not getting the speed I pay for? If results from FAST.com and other internet speed tests (like dslreports.com or speedtest.net) often show less speed than you have paid for, you can ask your ISP about the results.
Netflix has clear recommendations for speed based on the quality of video you want. Just know that the speeds listed are for streaming on a single device, so if multiple devices on your network are watching Netflix at the same time, you need enough speed to handle all those streams at once.
Some types of internet connections can experience slowdown at peak-use hours. Fast internet connections also need fast Wi-Fi routers that can handle multiple devices streaming at the same time. Watching a movie on Netflix uses more bandwidth than surfing the web, Voice over IP, or even online gaming. As such, one of the most basic reasons to upgrade your internet service is to make sure that the video you stream has a crisp, clear picture and buttery-smooth playback.

Hi All, I have this issue since 2 days. My macbook is connected to my tv through an hdmi cable and whenever I want to stream a movie, it plays fast forward like x 30. this happens only if the audio is set on the TV. If I set the sound again to macbook, this problem disappears. How can I fix it?
Same problem, my 14" macbook pro connected to my avr while trying to use apple TV +. I don't think it's a problem with the TV as stated here because it was plugged in the avr for me and I have a projector. It did start after I switched from my laptop speakers to the avr sound. Did you find a solution?
The issue you're describing ultimately sounds like it may be an issue with your TV or possibly the content you're attempting to watch. We'd suggest checking the information in this support article to be sure you're using the right connection set up: Connect to HDMI from your Mac - Apple Support
If HDMI is connected properly, try watching some different content in a different app to see if that makes a difference. Also, you may need to reach out to the manufacturer of your TV for more guidance.
@Sparks0829 This is definitely not an issue with specific content. Moreover, it's not specific to HDMI; it also happens through a Thunderbolt-DP cable. All content is like this, be it something played via YouTube, a local content played using QuickTime player, and even screencasts that I made. One difference is that YT content (probably because it's streaming) quickly forwards, stutters and then hangs in the middle, while local content just whizzes by to the end. It's almost as some piece of multimedia subsystem continuously failed to play one media chunk after another, but I'm just speculating.
I started experiencing it a couple of days or weeks ago (it was not there before, and I didn't make any changes to my hardware except from connecting and disconnecting headphones). Here's my setup: 16-inch MBP (M1 Pro), Sonoma 14.4.1. Video goes through a Thunderbolt-DP cable to a Gigabyte G4WCQ A monitor, and then, using a regular audio cable, to external speakers. There's usually an OWC 11-port Thunderbolt dock in between, but I've also tried without it, to the same result. I also tried without the external speakers, just using the monitor's built-in ones. Surprisingly, even restarting the coreaudio daemon doesn't help, so the issue must be somewhere deeper. The only thing that helps is a full reboot or disconnecting the monitor and switching to the built-in audio device.
Series played on HBO Max, for example, progress at about a 30x rate, meaning I see mostly individual frames and buffering animations (which, oddly, play at normal speed) -- it looks like videos are basically stuck in fast-forward.
Video playback is sped up across multiple browsers (Chrome, Safari), and playback of local files appears to be affected as well (the first I play a local file, it just skips to the end immediately, the second time seems fine). The issue with the playback speed of streaming video is reproducible on two entirely separate Macbooks when I connect them to this monitor, an LG 29KW600.
Now just got to work out why this is the case. My suspicion is routing the audio across the connection to the display is triggering some bug or undesired protocol transition. Keeping the audio off the display is the key to resolving this at the moment.
And while 15 Mbps might be enough for watching Netflix, remember that that's enough internet speed for only watching Netflix. So you'll need faster speed to cover any other connected devices or internet users in your home.
We recommend grabbing at least 50 Mbps download speeds if it's just you and maybe one other person using the internet. As for families, we think 100 Mbps or more download speed is better.
That's because you'll likely have other devices (like cell phones and home security systems) using the internet connection at the same time you're streaming Netflix. Not to mention other people too. The last thing you want is for your home security camera to lag out or for your kiddo's Netflix app playing Paw Patrol to buffer, right?
We recommend an internet plan with at least 50 Mbps download speeds if you enjoy streaming Netflix. And maybe even higher if you want HD streaming. Typically, the best internet speed for streaming video is around that speed, because 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.
Xfinity is available almost nationwide, and its prices are competitive. You'll easily find a well-priced 100 Mbps plan, like the Connect More plan. Just note that Xfinity plan names and prices change depending on where you live.
Its fiber network and up to 2300 Mbps download speeds make Verizon Fios Home Internet a shoo-in. Not to mention its symmetrical upload speed and download speed. But what really makes this ISP great is its reputation for amazing customer service.
CenturyLink offers unlimited data on all of its internet plans, which earns it bonus points when it comes to budget friendliness due to the lack of monthly overage fees. Its Fiber Internet plan is one of the cheapest gig-speed plans out there, perfect for streaming Netflix with your extended family or multiple roommates. Plus, your upload speed and download speed can reach up to 940 Mbps, which is pretty high compared to most internet service providers.
Keep in mind, these speeds are only relevant to Netflix's streams, which top out at 4 Mbps. Google's fiber service advertises a maximum download speed of 1,000 Mbps, and Verizon FiOS has top speeds of 300 Mbps.
Unlike web browsing, which starts and stops with each click, streaming video requires a constant flow of data over the network. A sudden change in speed or response time can stall videos and reduce the picture quality. The heavy demands that the streaming video places on networks has contributed to Comcast, Time Warner Cable (TWC) and others' moves toward monthly data caps.
Speed isn't the only factor in determining streaming video quality, but it's an important one. For the most part, fiber-based broadband services were the fastest in Netflix's test, followed by traditional broadband, DSL service and 4G wireless service. 3G wireless brought up the rear.
Fiber is a great service for those who are lucky enough to have it, but if you're not one of them, don't hold your breath. Bringing fiber to the home is an incredibly expensive proposition. A Goldman Sachs (GS) research note on Tuesday estimated that it would cost Google $140 billion to build its fiber network across the country. Verizon, which attempted a similar endeavor with its FiOS network, has said that it won't expand the offering to any new markets.
For the most part, cable providers run copper lines to their customers' homes, which offer significantly slower speeds. To bring higher speeds to customers without breaking the bank or ripping up people's yards, many companies are compromising by bringing fiber connections as close to the home as possible -- usually to an Internet core router or "node" that serves an entire neighborhood.
AT&T (T), for instance, announced last month that it would expand its previous plans to bring fiber to the neighborhood level for its U-Verse service -- which ranked 11th in Netflix's list. The plan will cost a total of $14 billion -- a tenth of what it would cost to bring fiber to every home, according to Goldman Sachs.
