預期結果:

• ## Performance Review Report **Target:** services/payment/ ### Performance Issues - Database queries in hot loop - consider caching - Missing connection pooling configuration - Unnecessary memory allocations in critical path ### Optimization Opportunities - Add Redis caching layer for frequently accessed data - Implement batch operations for bulk inserts - Use sync.Pool for object reuse ### Recommendations - Profile with pprof to identify bottlenecks - Consider connection pool sizing adjustments - Review indexing strategy for query patterns
