No fake/random values: download and upload are calculated from real bytes transferred between this browser and Cloudflare's speed-test edge. Ping/jitter are calculated from real request timing. A normal webpage cannot truthfully read your ISP package (for example “20 Mbps line”) or the Wi‑Fi radio band (2.4/5/6 GHz), so those are never guessed.

Download speedHow fast data reaches you. Higher is better for browsing, streaming and downloading.
Upload speedHow fast your connection sends data. Important for video calls, cloud backup and file uploads.
PingResponse delay. Lower is better for calls, games and other real-time activity.
JitterHow much ping varies. Lower and more stable jitter is better.
Speed changes from moment to moment. This result is the actual throughput measured to the test server during this run; it is not a guessed ISP package speed.
