How SpeedCheck Works

SpeedCheck measures your internet connection using multiple parallel streams of incompressible data. Latency is calculated as the median of repeated small probes; jitter is the median variation between them. Download and upload tests discard the initial TCP ramp-up period for stable, accurate readings.
