Interpret results
Use this guide to understand shared results and what your own test means.
What each metric means
- Download shows how fast data arrives for streams and file downloads.
- Latency is round-trip delay to the server.
- Jitter is variation in latency; lower is smoother.
- Packet loss (if shown) indicates dropped data on the path.
What good looks like
- Download: 25+ Mbps for 4K streaming; higher helps busy households.
- Latency: under 30 ms feels snappy; 30–60 ms is OK; 60+ ms can feel laggy.
- Jitter: under 5 ms is good; 5–20 ms is mixed; 20+ ms can cause stutter.
Common scenarios
- Streaming: stable download matters most, with low jitter.
- Gaming: latency and jitter matter more than headline Mbps.
- Video calls: low jitter prevents stutter and dropouts.
- Large downloads: higher Mbps reduces wait times.
What to try next
- Compare Wi‑Fi vs Ethernet.
- Restart your router and retest.
- Reduce background uploads.
- Test at different times of day.
FAQ
- What does “masked IP” mean on the Results page?
- Raw IPs are not displayed; a masked form or server-side hash is used for privacy.
- How do I share my results?
- Use the SHARE command in the terminal to opt in.
- Why are there no upload results?
- Laggy.uk currently focuses on download performance; upload is not measured.
