About This Tool

The tool performs active measurements to quantify internet performance across multiple servers. It reports download and upload speeds, latency, and jitter with standardized units for reliable comparisons. The measurement process targets configurable test servers and uses controlled data transfers to produce reproducible results.
Conceptually, it selects one or more test servers, initiates parallel streams, and measures data transferred over a defined period. It computes throughput as data divided by time in Mbps, collects RTT samples for latency, and derives jitter from RTT variability. A warm-up phase reduces bias from initial transfers and results are normalized for cross network interpretation.
Who benefits includes end users troubleshooting home or mobile connections, IT teams validating enterprise links, and developers building bandwidth-sensitive applications. Unique value comes from broad server coverage, adjustable test parameters, export options, and explicit confidence indicators that help distinguish stable measurements from transient anomalies.
Core features include region/server selection, duration control, protocol options, data export, and API access. Use cases span daily performance checks, post-change validation, and capacity planning, all while maintaining a focus on accuracy, repeatability, and interoperability with monitoring systems.

How to Use

  1. Provide inputs: select test region or server, set test duration and optional parameters such as sample count and protocol.
  2. Start test: initiate the measurement with the configured settings.
  3. Wait for completion: the tool completes transfers and computes metrics.
  4. Review outputs: examine download/upload speeds, latency, jitter, and data consumed.
  5. Optional: run additional tests over time and export results as JSON or CSV.

Frequently Asked Questions

Find Quick Answers

How are results calculated and what do the numbers mean?
Results are based on active measurements: throughput = total data transferred divided by duration, reported in Mbps; latency is the average RTT in milliseconds, jitter is the standard deviation of RTT, and packet loss is the percentage of failed packets. These metrics reflect current network conditions during the test.
Can I test using IPv6 or specific regional servers?
Yes. The tool supports both IPv4 and IPv6 when available on the selected servers. You can choose a region or a specific test server to influence routing and measurement accuracy based on proximity and server load.
Is exporting results available and in what formats?
Results can be exported for analytics and auditing. Supported formats include JSON and CSV, suitable for ingestion into monitoring stacks or data warehouses.
What should I consider when interpreting the results?
Interpretation should account for test conditions such as time of day, client hardware, VPN usage, and background traffic. Use multiple tests over time to establish performance trends and reduce the impact of transient spikes.
