Understanding Broadband Speed, Latency, and Bufferbloat
Evaluating internet connection quality requires measuring more than raw megabits per second (Mbps). Real-time applications like video conferencing, competitive gaming, and VoIP calls depend on stable packet delivery and minimal latency variance (jitter).
Download & Upload Throughput
Download speed measures how rapidly data transfers from edge servers to your device. Upload throughput measures your upstream bandwidth for video streaming, cloud backups, and file sharing.
Ping Latency & Jitter
Ping represents round-trip network packet transit time measured in milliseconds (ms). Jitter measures the statistical variance between consecutive latency samples; lower jitter ensures smooth real-time voice and video.
Bufferbloat Loaded Latency
Bufferbloat occurs when home routers buffer excess packets during heavy traffic, causing latency spikes from 20ms to over 500ms. This test measures loaded latency under active download and upload saturation.
Testing Methodology and Client Privacy
All speed tests stream uncompressible binary payloads over concurrent HTTP streams directly in your browser memory. Network diagnostics and performance histories remain on your local device hardware. No IP addresses, speed test telemetry, or location profiles are sold or logged on external advertising servers.
