Welcome to the Cerbi Benchmark Suite, a comprehensive and transparent comparison of popular .NET logging libraries. This repo leverages BenchmarkDotNet to evaluate performance, memory footprint, and encryption overhead in structured logging scenarios.
🧪 Public and reproducible — clone this repo, run it locally, and validate results yourself.
- CerbiStream (v1.1.1)
- Serilog (v2.12.0-preview)
- Microsoft.Extensions.Logging
- NLog (v5.4.0)
- Log4Net (v3.0.5-preview)
All tests were executed with both plain and encrypted logging configurations.
- CerbiStream performs comparably to Serilog and significantly faster than Microsoft Logging.
- NLog and Log4Net are fastest in raw log scenarios but lack encryption/governance features.
- CerbiStream maintains a minimal memory footprint even with encryption enabled.
- Serilog's rich pipeline comes at the cost of 4–5x more memory allocation.
- Tooling: BenchmarkDotNet v0.14.0
- System: Intel i9-9900K / .NET 8.0.13 / AVX2
- Run Mode: 10 iterations, 3 warmups per method
- Destination: In-memory/null sink to exclude I/O bottlenecks
- Encryption: Lightweight AES-style logic applied consistently across libraries
- ✅ CerbiStream balances encryption, governance, and low allocations with strong mid-tier performance.
- 🧠 Microsoft.Extensions.Logging is noticeably slower when encryption is added.
- 📉 NLog/Log4Net offer ultra-low latency but lack modern enterprise features like compliance validation.
