dev.perf-multipart-upload Calculator
Calculates optimal multipart upload part size, concurrency, and total upload time from file size and network throughput in a application performance engineering context. S3 multipart upload is required for objects above 5GB and recommended above 100MB — parallel parts with 8-25MB chunk size typically maximises throughput.
Inputs
Gb
Reference formula or conversion factor shown for context.
Mbps
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Parts
Reference formula or conversion factor shown for context.
Results
part size
Size of each multipart upload chunk. AWS S3 optimal: 5-100 MB. Smaller parts increase requests; larger parts increase re-upload cost on failure.
part count
Total number of items or occurrences.
transfer time
The computed duration or time value.
total size
The combined total across all inputs and components.
