Bandwidth Tester

The Bandwidth Tester measures key network performance metrics between a user device and a chosen test server. It produces throughput, latency, jitter, and packet loss figures to help IT professionals, network engineers, and developers validate connection quality, compare paths, and track changes over time. Results support capacity planning, SLA verification, and vendor or route benchmarking. It is suitable for office networks, data centers, and remote sites.
Conceptually, the tool sends controlled test traffic using configurable parameters such as test duration, parallel streams, protocol (TCP or UDP), and packet size. It aggregates data across streams to compute Mbps throughput, latency in milliseconds, jitter, and loss percentage. It guards against clock drift, handles timeouts, and scales tests from small offices to data center links.
What makes this tool valuable is its reproducibility, automation readiness, and clear outputs. Users can run geo-distributed tests, simulate various load scenarios, and compare results across time, devices, or providers. Advanced options produce percentile statistics, export CSV or JSON, and store results for dashboards or audits. It adheres to standard measurement practices while remaining simple to operate.
Use cases include verifying new broadband upgrades, validating fiber performance after deployment, assessing path performance during routing changes, and troubleshooting intermittent congestion. Outputs are designed to be machine readable for automation and human readable for reports. The tool prioritizes accuracy, stability, and actionable thresholds to guide optimization and vendor negotiations.
