This graph shows round-trip latencies of circuits used for downloading static files of different sizes over Tor, either from a server on the public internet or from an onion server. Round-trip latencies are measured as the time between sending the HTTP request and receiving the HTTP response header. The graph shows the median of measurements as thick line, the range of measurements from first to third quartile as ribbon, and the highest and lowest non-outlier measurements as thin lines.
