I/O Optimization

Definition

I/O optimization refers to techniques used to improve the input/output performance of a system, especially in the context of data processing and storage. This process aims to minimize latency and maximize throughput by efficiently managing how data is read from and written to storage devices. Effective I/O optimization is crucial when utilizing advanced numerical modeling techniques, as these often involve large datasets that require swift and efficient handling.
