Distinguish body-per-time ratios from connection speed
The transfer reference is received body size divided by elapsed time. It is not an internet connection-speed test.

가상 계산 / Illustrative calculation 100 KiB ÷ 0.5 s = 200 KiB/s 경과 시간에는 연결·이동 등이 포함 / elapsed time includes connection and navigation
Steps to verify
- Read size and time together.
- Compare equivalent content.
- Do not report it as connection Mbps.
How to interpret the result
The denominator includes the full fetch, unlike download-only bandwidth. For tiny bodies, connection time has a larger relative influence.
Deciding what to do next
Use final responses and repeated observations when judging changes. A high ratio does not establish fast screen rendering.
Feature scope
Measure the received body and elapsed fetch time from the Korean server, not all assets, rendering, pure TTFB or a Core Web Vitals score.
Frequently asked questions
Does it describe my network quality?
It is a server-request reference ratio. User connections require separate measurement.
