Bounded transfer
Transfer check
Choose one fixed sample size to inspect a single same-origin transfer. The tool cannot accept a custom host, path, port, or byte count.
Run one fixed transfer
Each button starts exactly one request. A new run cancels the previous one, and every request stops after 20 seconds.
No transfer check has been started.
What this measures
The result separates total request time, time to first byte (TTFB), and response-body transfer time. The displayed rate uses only the body-transfer window, so request latency is not reported as bandwidth. These fixed samples are intentionally small and are not a full line-speed benchmark; very short transfers are shown without a rate because the estimate would be unstable.
