Memory Access Latency

Memory Access Latency is the time delay between a processor requesting data from memory and receiving it. As trading algorithms become more complex and data-intensive, the speed at which the system can access and process information becomes a major performance bottleneck.

Minimizing memory latency involves optimizing data structures to fit into CPU caches, using efficient memory allocation patterns, and avoiding unnecessary data copies. High memory latency can slow down even the fastest algorithms, negating the benefits of low-network latency.

It is a critical factor in the design of high-performance trading software. By carefully managing how data is stored and accessed in memory, developers can significantly improve the speed and responsiveness of their trading systems.
