## Memory Controller Efficiency

Memory controller efficiency determines how effectively the system manages data flow between the CPU and system memory. It handles the scheduling of memory requests, ensuring that the processor is not left waiting for data.

In a trading environment, the controller must manage concurrent requests from multiple cores while maintaining low latency for critical path operations. High-efficiency controllers use sophisticated algorithms to reorder requests and prioritize time-sensitive financial transactions.

Understanding the behavior of the memory controller is essential for diagnosing performance issues in complex trading infrastructure.
