Cpu Speed Test Comparison

Your internet can be slow for many reasons. Your internet plan may be too slow for your needs, your modem or router may be out of date, your router may be on the fritz, or you might have too many people using your Wi-Fi at the same time. We can help you identify where the problem is and how to fix it.
You can improve your internet speed by upgrading to a faster plan, updating your equipment, or taking simpler measures like closing out apps and browser windows. We can walk you through 10 steps to improve your internet speed in just 15 minutes.
The fastest internet providers are Google Fiber, Verizon Fios, Xfinity, Metronet, and Cox. All of those internet providers offer fiber or cable internet plans with gigabit speeds. See our report on the Fastest Internet Providers.
If you see inconsistent results, there might be a bottleneck on your end. You can troubleshoot poor internet speeds with our guide on how to fix slow internet. But your internet connection may just be slow either from your plan or your internet type.
The time (measured in milliseconds) it takes for a signal to travel from your device to an internet server and back. Lower latency means your connection has a better response time for activities like gaming and livestreams.
Internet plans with multi-gig speeds as high as 2, 3, 5, 10 or even 50 gigabits per second (that's 50,000Mbps) are starting to emerge from many providers, including AT&T, Comcast, Frontier, Verizon Fios, Ziply Fiber and others. Plans like those are overkill for most homes, at least for now. The ideal is a symmetrical internet connection with uploads that are just as fast as the downloads. Speeds of 100Mbps would be perfectly fine for most homes.
Wi-Fi will almost always be slower than an Ethernet connection. Moving away from your router can further hinder your speeds. If there are walls or other obstructions between your router and the device you're using, this could cause your internet speed to fall.
In other instances, your internet speed can fluctuate depending on peak usage hours. Possibly worst of all, if your internet provider enforces data caps or throttles connections to help maintain overall network performance, you'll experience noticeable hits to your internet speed.
Keep this in mind when running a speed test and take measures to mitigate potential speed disruptions. For example, moving closer to the router can help get more accurate results. For the best result, try testing over an Ethernet connection, if possible. Also, consider running a few speed tests throughout the day to know how your speeds fluctuate at different times.
Many nationwide internet providers, like Google, Spectrum, Verizon and Xfinity, offer speed tests on their site. While using their service-specific tests is convenient, we recommend using one separate from your provider for a greater sense of objectivity.
While both internet speed tests are good options to determine your connection's strength, each has pros and cons. Since Fast.com is owned and operated by Netflix, it's a great test for online streamers relying on decent bandwidth. It's not as in-depth as Speedtest.net for providing analytics and doesn't let users specify which server they'd like to connect with. Speedtest.net, on the other hand, has a strong reputation for consistency, but it has banner ads that may slightly affect its test results.
Speed tests won't do anything to change the speed of your home's Wi-Fi network, but they're a great diagnostic tool; a quick way to check how your network is performing in various spots around your home.
The best way to put speed tests to use is to run them on your phone or laptop in various rooms throughout your house. If you find a dead zone where speeds come crashing down, you might want to consider putting a range extender in the closest room to that dead zone where speeds are strong. From there, it'll rebroadcast your Wi-Fi signal and potentially speed things up. If you find multiple dead zones in places where you'd like to connect, it might be time to upgrade your router. For the best whole-home Wi-Fi coverage, consider going with a mesh router that uses multiple devices.
One of our favorites is the Ookla speed test, which has a strong reputation for consistency and is one of the first speed tests on the web. We like Ookla for having everything you need from a speed test: accuracy, the ability to view your speed test history (when you create an account), a wide array of servers to connect to and even a handy app for speed testing from your Android or iOS device. Ookla's speed test is also the one we use when we're testing Wi-Fi routers. How much speed do you actually need? Here at CNET, we believe that you will need at least 100Mbps in usage to optimize streaming services. Check our top picks for the best Wi-Fi routers to optimize your Wi-Fi network.
Ookla has done a good job keeping up with the times by adding new features and capabilities. Two years ago, the service released a video-specific speed test that measures your network's ability to handle 4K video streams, and it also offers its own VPN service. In addition to the website and smartphone apps, Ookla has apps you can run on Windows or Mac. You can even run the Ookla speed test on an Apple TV.
One minor downside: Ookla does display banner ads while you run basic speed tests. It's not a huge deal, although it might slightly impact your results, depending on the strength of your connection at the time of the test.
Fast.com is another great broadband test, and the interface is as simple as possible. Plus, one of its biggest advantages is that Netflix owns it. That makes it a great pick for online streamers because the test is structured to see if your connection is strong enough to stream Netflix in maximum resolution without buffering.
While Fast.com is a great tool for some, it won't be the most helpful test for all users. The basic interface is easy to use but lacks some advanced settings and metrics you'll find with other speed tests. Most notably, you can't specify which server you'd like to connect with for your test.
All of these speed tests are simple to use, but the M-Lab Internet Speed Test is probably the easiest. Short for Measurement Lab, the open-source M-Lab test was developed by a collection of computer scientists and academic researchers with Google's backing. It's the test that pops up whenever you type "internet speed test" into the Google search bar. After agreeing to the data policy, click the "Begin" button to see your download speed, upload speed and latency within seconds.
That's about as simple as it gets because you won't need to bookmark it or remember exactly what it's called. There are no ads while you run the test; the only data shared with M-Lab is your IP address. Just know that the M-Lab test doesn't let you pick which server you'll use during the test, and it's designed for internet speeds of only up to 700 Mbps. You'll need to turn elsewhere if you're trying to speed-test a gigabit connection. Finally, your speed tests should not exceed to four times a day, as M-Lab recommends.
If you're looking for a test that looks at speed and consistency, Speedof.me is the way to go. Like Ookla, the test interface shows fluctuations in your upload and download speeds. Over time, that can make it easier to spot when something is amiss with your connection, especially since Speedof.me lets you compare your results with previous tests. Its mobile-friendly website is also great for running tests on your phone, allowing you to do a quick speed test on the go without downloading an app.
Speedof.me isn't a perfect option. For starters, there's no option for manually selecting which server you connect with. If home networking isn't your forte, the visualized data might seem more confusing or overwhelming than something like Fast.com, which gives you a number.
Testmy.net is an internet speed test that runs entirely on HTML5 and PHP. That means it doesn't require third-party software like Java or Flash to run your test, which can produce more accurate results. That also makes it a useful tool for comparing performance between different browsers. You can also create an account to track your internet speed for future reference or comparison.
It's not the most user-friendly tool. With a good deal of in-depth data, you'll have a lot of information to look through that might not be relevant to you. The design is also a little ugly by speed test standards, and it takes a few clicks before you begin a test, which isn't as streamlined as other speed tests that feature big "Go" buttons as soon as you load the page.
Running a speed test is usually as simple as finding the test and clicking the start prompt, but there are some extra measures you can take to get more accurate and informative results. Here are a few tips to consider when taking an internet speed test.
For over 20 years, we have used respectable sources, expert opinions and a hands-on approach to review data. We strive to personally test products and services to give insight to readers and offer them multiple options for what they're looking for. Our team has approved these internet speed tests through several factors, including speed, consistency, accessibility and browser compatibility. Ookla's speed test is the one we use when we're testing Wi-Fi routers, so we know from firsthand experience that it's reliable.
