When testing speed tests for the ultimate speed test test, after looking at the results below, it was noticed that the speed test can be divided into three categories.
See the page
Accuracy check for the details of the measurements.
These three categories are:
Realistic Mainstream Conservative Realistic
As described at the page
Internet speed with trial and error I concluded that the real internet speed
my ISP provides is 56Mbps instead of 50Mbps. Assuming 56Mps is delivered, it must be concluded that only a few speed tests show a realistic download speed.
These speed test are:
Comparitech Internet Speed at a Glance LibreSpeed SpeedOf.Me Speedsmart
Note that TheInternetSpeedTest.com and the Wi-Fi Internet Speed Test are in the graph but not in the list above.
Research showed that these speed tests are based on the code used for LibreSpeed.
The outcome of
the ultimate speed test test 2020
is that SpeedOf.Me is the most accurate speed test
when using the max. download speed.
Realistic speed tests
A realistic speed test gives an indication of the real download speed provided by your ISP.
This speed is probably higher than you expected. You can imagine your ISP delivering more speed
than agreed to minimize discussions about the service provided with customer service.
Ookla's Speedtest has been the speed test leader for years. It is the most commonly used speed test.
This is largely because
most ISP speed tests are based on the Ookla speed test.
Speed tests with results similar to the Ookla speed test are (besides the speed test of your ISP):
Broadband Speed Checker DSLReports Fireprobe ® Google Fiber Measurement Lab N Perf Ookla Speedtest SamKnows Speed Test TestMy.net Xfinity xFi Speed Test
the first ultimate speed test test compares speed tests in this category.
Based on that test, it was concluded that Google Fiber (
speedtest.googlefiber.net) has the best overall score,
Xfinity xFi Speed Test ( speedtest.xfinity.com) is most accurate and
Internet Speed at a Glance ( speedtest.zomdir.com) gives the quickest insight.
Mainstream speed tests
Since almost every ISP has a speed test based on Ookla's Speedtest, or recommends the Ookla Speedtest, it's not surprising that Ookla's results are considered the gold standard.
You might be wondering if a competitive speed test won't sideline itself if it deviates too much from Ookla's Speedtest?
It is therefore not surprising that there are so many speed tests that all give more or less the same result as Ookla's Speedtest.
Speed tests in this category usually gives as result a speed test that you expected. That's fine (although not correct).
After all these results will minimize the number of discussions about the service provided with customer service of your ISP.
Some speed tests which gives lower values as download speed. It is best to consider the results of these tests
as the lower limit. You can be confident that you will reach these internet speeds.
Speed tests belonging to this category are:
Bandwidth Place Cloudflare Fast RCN Speedtest Toast Internet Speed Test Conservative speed tests
A conservative speed test gives you a low download speed. This download speed is that low that you should consider it as the lower limit delivered by your ISP.
For Fast, the speed test of Netflix, that is actually not at all wrong. If you achieve
the minimum required speed for Netflix with the Fast speed test, you will almost
certainly have no problems with watching Netflix. You can probably imagine without
a doubt that this will prevent a lot of phone calls to the Netflix support center.
