Zero Copy Processing
Zero copy processing is a technique that avoids the need for the CPU to copy data between memory buffers, thereby reducing memory bandwidth usage and CPU cycles. In a trading context, this is used to process incoming market data packets directly from the network interface card into the application memory.
By eliminating unnecessary data copies, the system can handle higher volumes of traffic with lower latency. This is crucial for systems that must process thousands of market updates per second.
It allows the hardware to focus on the trading logic rather than data management tasks. This technique is a standard optimization for high-performance financial software.
