Implement V11ComponentsTest for testing high-performance mode, dynamic pool, middleware integration, performance monitoring, memory management, and factory pooling. - Create HighPerformanceStressTest to evaluate concurrent request handling, pool overflow behavior, circuit breaker functionality, load shedding effectiveness, memory management under pressure, and graceful degradation under resource exhaustion. -
