What this internet speed test measures

StrixSpeed runs three separate measurements against this server and reports each one on its own. Together they describe almost everything you feel day to day — how quickly pages load, how smoothly video calls hold up, and whether a large download finishes in seconds or in an afternoon.

Download speed (Mbps)
How fast data reaches you. This is the number that decides how quickly a page loads, how many 4K streams your household can run at once, and how long a game update takes. It is the figure internet providers advertise.
Upload speed (Mbps)
How fast data leaves your connection — sending files, backing up to cloud storage, and your own camera feed on a video call. Cable and DSL lines usually upload far slower than they download; fibre is typically symmetric.
Ping / latency (ms)
The round-trip time for a single small request. Low latency matters more than raw bandwidth for online gaming, video calls and remote desktops. Under 30 ms is excellent, under 60 ms is fine for almost anything, and over 150 ms is noticeable as lag.

How much speed do you actually need?

More speed is not always worth paying for. These are realistic download requirements per simultaneous activity — add them up for everyone in the household at once.

If your measured speed comfortably covers what you actually do, a faster plan will not make your connection feel quicker. A high ping or unstable Wi-Fi is far more often the real cause of a connection that feels slow.

Getting an accurate result

  1. Stop other downloads, streams and cloud sync before testing — they share the same line.
  2. Test over Ethernet if you can. Wi-Fi, especially 2.4 GHz, is often the bottleneck rather than the connection itself.
  3. If you must use Wi-Fi, move close to the router and prefer the 5 GHz or 6 GHz band.
  4. Turn off any VPN. Encrypting and re-routing traffic reliably lowers the measured result.
  5. Run the test a few times at different moments. Networks are congested at peak evening hours.

Frequently asked questions

What is a good internet speed?

For most households, 50–100 Mbps download is comfortable, and anything above 25 Mbps handles 4K streaming. What matters is whether your speed covers everything happening on the connection at the same time, not the headline number on your plan.

What is the difference between download and upload speed?

Download speed is how fast data comes to you, which affects streaming, browsing and installing updates. Upload speed is how fast data leaves your device, which affects sending files, cloud backups and how others see you on a video call. Most cable and DSL connections are asymmetric, with upload far slower than download.

What is ping, and what counts as a good ping?

Ping is the round-trip time for a small request, measured in milliseconds. Under 30 ms is excellent, under 60 ms is good, and above 150 ms produces noticeable lag in games and video calls. Ping depends mostly on distance and routing, so it does not improve by buying a faster plan.

Why is my result lower than the speed I pay for?

Advertised speeds are the maximum the line can carry under ideal conditions. Wi-Fi interference, an older router, a busy network, a VPN, background downloads on other devices, and congestion at peak hours all reduce what you actually get. Testing over Ethernet with everything else idle shows the closest thing to your true line speed.

Does StrixSpeed store my results or track me?

Results are calculated in your browser and are never saved to a database or tied to an account — there is nothing to sign up for. Reloading the page clears everything.

How much data does a speed test use?

Roughly your connection speed multiplied by the length of the test. Each phase runs for about six seconds, so a 100 Mbps connection transfers in the region of 75 MB for the download phase. Be careful on a metered or mobile plan.
