Methodology
What We Measure
Each benchmark uploads and then downloads a 10 MB file to a bucket in each provider, measuring the time for each operation independently.
Three metrics are captured per iteration: upload latency, download latency, and throughput (Mbps, computed from total transferred bytes over total operation time).
Each provider is tested with 100 iterations per run. Benchmarks run automatically via GitHub Actions on a recurring schedule. All results are committed to the public benchmarks repo.
How We Score
The Composite Score is a weighted blend of upload and download latency metrics multiplied by the success rate. Latency is scored against a fixed 5-second ceiling: 100 × (1 − value / 5,000ms).
The weighted score is multiplied by the success rate (0–1), so providers that fail frequently are penalized proportionally.
