      tools: [profiler, APM, database_explain]
      metrics: [p50_latency, p99_latency, throughput]

optimizations:
  - database_query_optimization:
      sparc_phase: refinement
      actions: [add_indexes, optimize_joins, implement_pagination]
      expected_improvement: 30%
      success_metric: "p99 < 100ms"

  - implement_caching_layer:
      sparc_phase: architecture
      actions: [redis_setup, cache_warming, invalidation_strategy]
      expected_improvement: 25%

  - code_optimization:
      sparc_phase: refinement
