 ### 1. Unit Tests (`pkg/*/`)
 
+### 2. Benchmarks (`pkg/*/_benchmark_test.go`)
+
+Performance benchmarks measure the speed of critical operations. Run benchmarks to:
+- Detect performance regressions
+- Identify optimization opportunities
+- Track performance trends over time
+
+**Running Benchmarks:**
+```bash
+# Run all benchmarks
+go test -bench=. -run=^$ ./pkg/...
+
+# Run benchmarks for specific package
+go test -bench=. -run=^$ ./pkg/workflow/
+
+# Run specific benchmark
+go test -bench=BenchmarkCompileWorkflow -run=^$ ./pkg/workflow/
+
+# Run with custom iterations
+go test -bench=. -benchtime=100x -run=^$ ./pkg/workflow/
+
+# Save benchmark results for comparison
+go test -bench=. -run=^$ ./pkg/... > bench_baseline.txt
+```
+
+**Benchmark Coverage:**
+- **Workflow Compilation**: Basic, with MCP, with imports, with validation, complex workflows
+- **Frontmatter Parsing**: Simple, complex, minimal, with arrays, schema validation
+- **Expression Validation**: Single expressions, complex expressions, full markdown validation, parsing
+- **Log Processing**: Claude, Copilot, Codex log parsing, aggregation, JSON metrics extraction
+- **MCP Configuration**: Playwright config, Docker args, expression extraction
+- **Tool Processing**: Simple and complex tool configurations, safe outputs, network permissions
+
+**Performance Baselines** (approximate, machine-dependent):
+- Workflow compilation: ~100μs - 2ms depending on complexity
+- Frontmatter parsing: ~10μs - 250μs depending on complexity
+- Expression validation: ~700ns - 10μs per expression
+- Log parsing: ~50μs - 1ms depending on log size
+- Schema validation: ~35μs - 130μs depending on complexity

Subject: [PATCH 5/5] Optimize benchmark suite to run under 1 minute

- Reduced benchtime from default to 3x iterations for CI
- Fixed BenchmarkExpressionSafety to use only allowed expressions
- Updated bench-compare to use 100x for more accurate measurements
- Benchmark suite now runs in ~6 seconds (well under 1 minute)
- Updated TESTING.md with optimized benchmark usage
