How to use
Set data size, line speed, and efficiency with their units to estimate transfer time, or work backward from a deadline to required speed.
The basic time is bytes × 8 ÷ effective bits per second. Compare several efficiency assumptions. This is an estimate, not a measurement of congestion or storage speed.
Examples
1Principles and limits
Each input is limited to 1,048,576 bytes, output to 33,554,432 bytes, and processing to 5,000 ms. Input is never silently truncated.
