# Benchmark

**Status:** Implemented
**Source:** `src/Bench/`
**Owner:** Platform Team

## Purpose

Benchmark provides performance testing and regression analysis for StellaOps components. Ensures deterministic scan times, throughput validation, and performance profiling for critical paths (scanning, policy evaluation, SBOM generation).

## Components

**Services:**
- `StellaOps.Bench` - Benchmarking harness with BenchmarkDotNet integration

**Key Features:**
- Scanner performance benchmarks (per-analyzer, full-scan)
- Policy engine evaluation latency tests
- SBOM generation throughput tests
- Database query performance profiling
- Determinism validation (output stability)

## Configuration

Benchmark configuration via BenchmarkDotNet attributes and runtime parameters.

Key settings:
- Benchmark filters and categories
- Iterations and warmup counts
- Memory profiling and allocation tracking
- Export formats (JSON, HTML, Markdown)

## Dependencies

- BenchmarkDotNet framework
- Scanner (benchmark targets)
- Policy Engine (benchmark targets)
- SbomService (benchmark targets)
- Test fixtures and datasets

## Related Documentation

- Architecture: `./architecture.md`
- Scanner: `../scanner/`
- Policy: `../policy/`
- Operations: `./operations/` (if exists)

## Current Status

Implemented with BenchmarkDotNet harness. Provides performance baselines for scanner analyzers, policy evaluation, and SBOM generation. Used for regression detection in CI/CD pipeline.
