What does the speed test do?

It measures three key metrics: ping (latency in ms), download (Mbps) and upload (Mbps). It also shows your provider, public IP and connection type so you have a complete picture of the network.

Each phase opens 4 parallel HTTP connections to saturate the link, like Speedtest.net does. The first 2 seconds are discarded (TCP slow-start warm-up) and the speed is computed only from the next 10 seconds — bytes ÷ time, in Mbps.

Is the measurement accurate?

Yes — using parallel connections and a steady-state window the measurement gets close to a real Speedtest. There's still some natural variation (5–15%) due to TCP/HTTP overhead, network jitter and the location of our server.

Is there a server near me?

ToolboxHub uses a single server, so latency depends on your region. The result reflects HTTP performance against that endpoint, which is usually a good proxy for everyday speed (streaming, downloads, video calls).

Why does each phase last about 12 seconds?

It's the time needed for TCP to leave slow-start (~2 s warm-up) and for us to gather a stable measurement window (~10 s). Less than that and the result reflects the warm-up; more than that and the test gets unnecessarily long.

Where do the provider and location data come from?

Provider, ASN, IP and location come from a public IP database (ipapi.co) when accessed from our server. The 'network type' (Wi-Fi, mobile, etc.) comes from the browser's NetworkInformation API, available mainly in Chromium-based browsers and on mobile.

Is the ping the same as in a game?

Not exactly. We measure HTTP latency to the ToolboxHub server, which is similar to but not identical to game ping (which uses UDP and dedicated servers). Still, it's a reliable indicator of overall network responsiveness.

About the Speed Test

Measure your download, upload, ping and jitter directly in the browser. The tool also shows your provider (ISP), public IP and approximate location, useful for spotting problems with the contracted plan, comparing Wi-Fi vs. cable or validating a 5G connection. To inspect a specific IP, use our IP Lookup.

How to test in 3 steps

1Click Start test to begin the cycle.
2Wait for ping → download → upload phases (about 30 seconds).
3Review each step's result and your connection details in the side panel.

Speed quality guide

The table below helps you understand whether the measured speed is enough for the most common uses.

Range	Typical use	Example
0–10 Mbps	Light browsing and email	SD video, social networks
10–25 Mbps	HD video and standard remote work	1080p streaming, video calls
25–100 Mbps	Multi-device home, 4K and downloads	4K streaming, online gaming
100+ Mbps	Heavy work, large files and many users	Game/video downloads, multi-user 4K
