How to Read a Speed Test
Understand download speed, upload speed, ping, jitter, browser conditions, and why repeated measurements can differ.
What the Main Numbers Mean
Download speed measures how quickly data reaches your browser. Upload speed measures how quickly data leaves your connection. Ping is round-trip latency, while jitter describes how much that latency changes between samples.
Why Two Tests Can Differ
Results can change because of WiFi signal, background downloads, device load, browser activity, ISP congestion, server distance, and route changes. One test is a snapshot, not a permanent rating.
How to Test More Reliably
Pause large downloads, close unnecessary tabs, keep the device near the router or use Ethernet, and run several tests at different times. Compare the pattern rather than one isolated result.
What SpeedMeter Actually Measures
SpeedMeter uses real browser requests to measure latency and transferred bytes. It does not invent Mbps values. Results describe the active browser session and current route.
When to Investigate Further
If speeds repeatedly fall far below what you normally receive, compare multiple devices, test Ethernet versus WiFi, review your ISP/network details, and check for congestion or local equipment issues.
