Speed tests

What is an internet speed test?

 

An internet speed test is a tool (website, app, program) that measures the maximum amount of data you can receive per second. This "downloadspeed" is expressed in megabits per second (Mbps).

Note that in most cases the bandwidth provided by the ISP is not measurable because the home network is the weakest link.

What makes a speed test excellent?

What makes a good speed test site?

 

A good speed test site is
1. Accurate and consistent
2. Free to use
3. Easy to use
4. Privacy friendly
5. Informative
6. Fast

With these requirements in mind, Google Fiber is the best speed test out there.

How to perform a speed test?

 

Assuming you want to know if your internet is working fine first check Internet Speed at a Glance. If you want to know your internet speed in detail, it is best to use Google Fiber.

Before you start measuring, check whether the home network you are using can handle the bandwidth to be measured. In general it's best to test with a wired network to rule out Wi-Fi issues. Because large downloads have a huge impact on the speed measured, it is recommended to test on an updated system as a sole user.

How do I test my true internet speed?

Can I trust the speed test of my ISP?

 

Short answer: Yes

Long answer:
More often than not, your ISP offers a speed test based on the Ookla Speedtest (a sample shows at least 5 out of 6). Such a mainstream speed test measures the download speed just as good as the Ookla Speedtest. The results of the Ookla Speedtest are structural significant lower than your real internet speed as measured by SpeedOf.me. Hence you might interpret the results of the speed test of your provider as a minimum speed you get.

Which factors have the greatest influence on your internet speed?

 

Large downloads (and TOR) have the biggest negative impact on your internet speed.

Speed determining factors

Does the test server used affect my internet speed?

 

The test server used does not affect your internet speed.

Depending on the speed test used, the test server used can affect the measured internet speed.

However, in most speed tests, the test server used does not significantly affect the measurement of your internet speed.

Speed determining factors (based on the first test)

Does the browser you use affect your internet speed?

 

As long as you use a modern browser (Chrome, Edge, Firefox), this will not affect your internet speed.

Speed determining factors

Speed determining factors

The Domain Name System (DNS) server you are using will not affect your internet speed.

Speed determining factors

Does using video streaming affect your internet speed?

 

Video streaming uses some of your internet speed. Your internet speed as provided by your ISP does not change.

Depending on the speed test used, the use of video streaming can affect the measurement of your internet speed.

Speed determining factors

Does using TOR affect your internet speed?

 

TOR uses a lot of your internet speed. Your internet speed as provided by your ISP does not change.

If you measure your internet speed while downloading files, the measured speed will be significantly slower.

Speed determining factors

How does VPN use affect your internet speed?

 

Depending on the VPN (Virtual Private Network) used, this can significantly affect your internet speed.

Research shows that there are major differences. There are VPNs that do not have a significant influence, but also VPNs that do have a significant influence.

Speed determining factors

Does the hardware used affect my internet speed?

 

The hardware you use (computer, Wi-Fi router, Powerline) can affect your internet speed.

This will be especially the case when the specifications of your hardware are less than the download speed provided by your ISP.

Note that the slowest part of your network determines your internet speed.

How does malware affect my internet speed?

 

The influence of malware on your internet speed cannot be determined generically. You can assume that malware is using some of your internet speed.

Hence, malware is likely to negatively impact your internet speed. How much that is depends on the malware on your system.

Does the location of the Wi-Fi router matter?

 

Wi-Fi uses a specific part of the radio frequency (RF) spectrum. Concrete, brick and masonry significantly dampen the radio signals used by Wi-Fi. The radio waves from a microwave oven interfere with Wi-Fi radio signals.

The location of your WiFi router can therefore greatly affect your internet speed.

Does time of day affect Internet speed?

 

The time of day can affect your internet speed. It depends on your internet subscription and the quality of your Internet Service Provider's (ISP's) network.

Wikipedia - Internet rush hour

How do other devices and users affect my internet speed?

 

Other devices and users will use some of the available internet speed. Your internet speed as provided by your ISP does not change.

If you measure your internet speed while other devices and users are using the internet, the measured speed may be slower.

This depends on the internet usage by the other devices and users.
