Details

• Threshold for regression warnings: >15% and ≥1ms absolute change
• Deltas in parentheses indicate that the absolute change is below the minimum threshold
• Each measurement discards the first (cold-cache) execution, then reports the median of all subsequent runs within a 5-second time budget
• Timings use clock_timestamp() with JIT compilation and synchronized sequential scans disabled
• Data: 1000 accounts, 100 events, 1000 contacts, ~1000 guests, 200 attendances
• Runner: GitHub Actions (timings may vary ±10% between runs)
• Workflow run
