  2  Example 8: Comprehensive Benchmark
  3  
  4  This example provides a comprehensive benchmark comparing Fast Context
  5  performance against traditional search approaches.
  6  
  7  Metrics measured:
  8  - Search latency
  9  - Throughput (queries per second)
 10  - Cache effectiveness
 11  - Parallel execution speedup

214     Fast Context provides:
215     ✓ Sub-100ms search latency for most queries
216     ✓ 100+ queries/second with caching
217     ✓ 100x+ speedup for cached queries
218     ✓ 2-5x speedup from parallel execution
219     ✓ 1000+ files/second indexing rate

222     rapid code search in AI agent workflows.
