What is Internet Speed Test?
Speed tests are the best way to see how fast your internet is. Internet service providers (ISPs) promise "up to" a certain speed in optimal conditions, but a speed test shows how fast or slow your connection is.

What is a Speed Test?
Internet speed test is the best way to get an idea of how fast your connection is currently. The service you connect to depends on the plan you choose, local congestion, restriction rules in it, etc. It usually limits download and upload speed according to your connection.
The trick is that your ISP almost always includes the phrase "most". If you are promised a speed of "up to 30 Mbps" and you consistently get only 28 Mbps, we can say that your service provider is keeping its promise. But if you see 10 Mbps, you're not getting what you paid for, and it's time to talk to your service provider.
Speed test measures your ping, download, and upload speed. Measuring the last two is crucial because most ISPs give separate promises for download and upload speeds. Usually the download speed stands out prominently, but if you get into details, the ISP usually sets a slower upload speed for each tier. For example, our local ISP offers a plan with a download speed of 50 Mbps, but an upload speed of 5 Mbps.
How Does Internet Speed Test Work?
You can easily test speed with TestSpeed.it
Once you select a server, ping, download, and upload tests are performed.
More than one thing happens when you start a speed test. TestSpeed.it Speed Test sends a simple signal (ping) to the server and responds. The test measures this round trip in milliseconds.
When the ping is complete, the download test begins. The client opens multiple connections to the server and tries to download a small piece of data. At this stage, two things are measured: how long it takes to capture the piece of data and how much of your network resources it uses.
If the client detects that you have free space, it opens additional connections to the server and downloads more data.
Imagine your internet service as a highway with a speed limit. Opening additional links is like adding more lanes to the highway. The speed limit hasn't changed, but more cars can cross the same territory faster; Thus, the 50th car will arrive earlier using a four-lane highway from a two-lane vehicle.
Once the client determines it has the right connections to test your internet service, it downloads additional data chunks, measures the amount downloaded in the allotted time, and offers the download speed.
Next is the load test. It's actually the same process as downloading, but the other way around. Instead of the client pulling data from the server to your computer, the client uploads data from your computer to the server.
Are Internet Speed Tests Accurate?
Speed tests sound simple, but accurately measuring your connection speed can be much more difficult than it seems. There can be many factors in speed testing.
Consider the first step of the process: selecting a test server. Often the nearest server can be incredibly close or even in the same city. This proximity is optimal, so the data is not far enough to go. Companies know that proximity matters, so some, like Netflix, use a content delivery network to bring data closer to you.
But not all of the Internet is close to you. Most are on remote computers, sometimes across the country or in another country. So although your speed test may show incredibly fast streams, you may find that downloading a program is very slow if the server hosting the data is far away. In this scenario, your results may reflect faster performance than your actual usage.
You may see different speed results when testing with TestSpeed.it. Your service provider may also offer a speed testing service. However, you probably shouldn't rely on a speed test created by your ISP. Provider tests are optimized for ideal conditions using servers located near you, usually kept in the same ISP network you are testing.
