What We Measure

Every benchmark measures Time to Interactive (TTI) — the elapsed time from calling compute.sandbox.create() to the first successful runCommand() inside the sandbox.

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.

Burst Test: All sandboxes are launched concurrently in a single burst.

How We Score

The Composite Score is a weighted blend of timing metrics multiplied by the success rate. Each metric is scored against a fixed 10-second ceiling: 100 × (1 − value / 10,000ms), so a 200ms median scores 98 and anything ≥10s scores 0.

The weighted timing score is then multiplied by the success rate (0–1), so providers that fail frequently are penalized proportionally.

• • Median: 60% — primary signal for typical experience
• • P95: 25% — tail latency / consistency
• • P99: 15% — extreme tail latency
