How to use Internet Speed Test

The short answer
To test your internet speed, press GO on the ClickZM speed test: it measures ping and jitter, then download and upload speed in Mbps over parallel connections to the nearest Cloudflare data centre, plus latency under load (bufferbloat), in about 20 seconds.
It runs in your browser. What you enter is not uploaded.
How to use it
Open the speed test and press GO. Leave the tab in the foreground until it finishes.
It measures ping and jitter, then download and upload speed over parallel connections to the nearest Cloudflare data centre.
Read the bufferbloat figure, which is the extra delay while the line is busy.
On Wi-Fi the result is your Wi-Fi speed. Repeat on Ethernet when you want the line speed.
Limits worth knowing
What is a good internet speed? 25 Mbps per person covers 4K streaming and video calls; gamers need a ping under 40 ms with low jitter, and homes with several people working online are best on 100 Mbps or more.
Is it a Wi-Fi speed test? Yes. It measures the device you run it on, so on Wi-Fi it shows your Wi-Fi speed and over Ethernet your broadband line speed.
Does it need an app? No. It runs in any browser on Wi-Fi, broadband, fibre or mobile data, with no signup.
