What do download, upload and ping mean?
Download is how fast data reaches you — it drives streaming, browsing and pulling in files. Upload is the opposite direction: sending files, video calls, backups. Ping is the connection's reaction time in milliseconds — the lower, the more instant everything feels. Jitter tells you how stable that reaction time is: a low value means a calm, predictable line.
How much speed is enough?
For email and browsing, 10 Mb/s is workable. A household streaming in HD is comfortable from 50 Mb/s; 4K and several devices at once call for 100–200 Mb/s. For video calls the upload matters just as much (count on 3–5 Mb/s per call), and for online gaming what counts most is a low ping — ideally under 60 ms.
Why is my result lower than my plan promises?
Providers promise speed up to your wall socket — everything after that is your own network. Wi-Fi far from the router, a VPN, older devices or housemates streaming at the same time all lower the result. For the cleanest reading, test over a cable, close to the router, without a VPN. If you consistently stay under 60–70% of the promised speed, a call to your provider is justified.
Fast internet, but a slow website?
Then it's not your connection — it's the site. That's exactly why Firmatic builds websites that load in a fraction of a second: statically built, served worldwide through a CDN, with no sluggish database.
