How Klyrix/speed measures your connection
Every Klyrix speed test runs in your browser against a Klyrix test server. There is nothing to install and no account to create.
Latency probes
Twenty tiny requests measure ping (the round-trip time), jitter (how much it varies) and packet loss before any heavy traffic starts.
Download
Several parallel streams pull data from the server, so one slow connection can’t hide your real capacity. The result is the sustained average, not a lucky peak.
Upload
The same idea in reverse: parallel streams push test data to the server to measure how fast you can send — essential for calls, streaming and backups.
Latency under load
While the line is saturated, we keep probing. A big jump means bufferbloat, the hidden cause of laggy calls and games on otherwise fast connections.
Glossary
What the numbers mean
- Download speed
- How fast data reaches your device, measured in megabits per second (Mbps). It matters for streaming, browsing and downloads.
- Upload speed
- How fast your device can send data out. It matters for video calls, live streaming, cloud backups and sending large files.
- Ping (latency)
- The time a tiny message needs to reach the server and come back, in milliseconds (ms). Lower is better, especially for gaming and calls.
- Jitter
- How much your ping varies from one probe to the next. High jitter makes calls choppy and games feel inconsistent, even when the average ping is low.
- Packet loss
- The share of probes that never came back. Even 1–2% loss can break up calls and cause rubber-banding in games.
- Latency under load (bufferbloat)
- Ping measured while your connection is busy. If it climbs sharply, your router is queuing too much data — the main reason a “fast” connection still feels slow.
- Stability
- A 0–100 score for how steady your speed stayed during the test. Big swings point to Wi-Fi interference, congestion or a flaky line.
FAQ
Frequently asked questions
How accurate is the Klyrix speed test?
It measures the real, sustained throughput between your browser and a Klyrix server using parallel streams, and reports the average rather than the peak. Results still depend on your device, Wi-Fi quality, other traffic on your network and the distance to the server. For the most accurate reading, use a wired connection and pause other downloads.
Why is my speed lower than the plan I pay for?
Plans advertise a maximum. Real speeds are shaped by Wi-Fi signal and interference, older devices or routers, congestion at busy hours and the server you test against. Try a wired connection next to the router; if you still see far less than your plan, share your results with your provider.
What is a good ping?
Under 20 ms is excellent, 20–60 ms is good for almost everything, and 60–100 ms is fine for streaming and browsing but noticeable in fast games. Above 100 ms you may feel lag in calls and online games.
What is the difference between Mbps and MB/s?
Providers advertise speeds in megabits per second (Mbps), while file downloads are usually shown in megabytes per second (MB/s). A byte is eight bits, so 8 Mbps equals 1 MB/s. Klyrix/speed can show either: tap the unit under the speedometer.
What is bufferbloat?
Bufferbloat is the extra delay that appears when your connection is busy: uploads or downloads fill the router’s queues and every other packet has to wait. It is why calls stutter while someone else is downloading. A grade of A or B means your connection stays responsive under load; smart queue management (SQM/QoS) on your router can fix poor grades.
How much data does a speed test use?
Each phase runs for a fixed time, so faster connections transfer more. A 50 Mbps line uses roughly 100 MB in a standard test, a gigabit line a gigabyte or more. The “Data used” gauge in your report shows the exact amount, and you can pick a quick test in Settings.
Why do results differ between runs?
Internet speed is never constant: other devices, congestion on your provider’s network and Wi-Fi conditions shift from second to second. Run the test two or three times and compare the stability score. Klyrix/speed keeps your recent results so you can see the trend.
Is Klyrix/speed private?
The test only transfers random data created for the test, and it never reads your files or browsing. Like any website, the test server sees your IP address, which is what lets us show your connection details. Your recent results are stored only in your own browser, and you can clear them anytime in Settings.
