Field notes
The available test performs real multi-stream transfers in the browser and reports throughput, ping, and jitter, using browser timing and trimmed-mean calculations. NetTestLab says it avoids predetermined estimates and discards network streams after processing; it also states that results and IP addresses are not stored in its application database. DNS resolver benchmarking and an HTTP/security-header inspector are listed as roadmap items rather than available tools.
