[Advanced] Performance Benchmarking Suite

[yasmramos]

Description

Create automated performance benchmarks comparing TailwindFX vs manual CSS styling.

Task

• Set up JMH benchmark project
• Create benchmarks for common operations:
  • Single utility application
  • Batch utility application (10, 50, 100 utilities)
  • JIT compilation time
  • Cache lookup performance
  • Memory allocation patterns
• Compare against manual CSS approach
• Integrate with CI/CD pipeline
• Generate trend reports over time
• Set up performance regression alerts

Benchmark Categories

1. Micro-benchmarks: Individual method performance
2. Integration benchmarks: Full apply() cycles
3. Memory benchmarks: Heap usage, GC pressure
4. Startup benchmarks: Cold vs warm cache
