Zero Copy Parsing
Zero copy parsing is a technique that allows a program to process data without having to copy it between different memory areas. In standard systems, data is often copied from the network buffer to an application buffer before being parsed.
This consumes CPU time and memory bandwidth. Zero copy techniques allow the application to read the data directly from the buffer where it was received.
This significantly reduces latency and increases throughput, especially for large volumes of data. It is a common optimization in high-performance networking and trading stacks.
By avoiding unnecessary memory operations, the system can handle more messages per second. This is critical for meeting the stringent requirements of modern electronic markets.
It is an advanced optimization that requires careful memory management.
