# Bench (Performance Benchmarks)

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

> **Note:** This folder documents **performance benchmarks**. For **competitive benchmarking** (accuracy comparison with other scanners), see [`../benchmark/`](../benchmark/).

## Purpose

Bench provides performance benchmark infrastructure for StellaOps modules. Measures throughput, latency, and resource usage to detect regressions and validate performance targets.

## Components

**Benchmark Projects:**
- `StellaOps.Bench.LinkNotMerge` - Link-Not-Merge correlation performance
- `StellaOps.Bench.LinkNotMerge.Vex` - LNM VEX statement performance
- `StellaOps.Bench.Notify` - Notification delivery throughput
- `StellaOps.Bench.PolicyEngine` - Policy evaluation performance
- `StellaOps.Bench.ScannerAnalyzers` - Language analyzer performance

## Usage

```bash
# Run all benchmarks
dotnet run -c Release --project src/Bench/StellaOps.Bench/LinkNotMerge/StellaOps.Bench.LinkNotMerge

# Run with specific runtime
dotnet run -c Release --project src/Bench/StellaOps.Bench/Notify/StellaOps.Bench.Notify
```
