How It Works
A transparent and reproducible benchmarking pipeline for .NET object mappers
⏱
Automated Execution
Benchmarks run automatically every 5 minutes on a dedicated VPS.
📊
Averaged Results
Results shown are the average of the last 50 runs, reducing noise and outliers.
🔄
Auto-Updated Libraries
Library versions are updated automatically so benchmarks always reflect the latest releases.
🎯
Multiple Scenarios
Each library is tested across flat mapping, nested objects, collections, and name differences.
