AIX Dynamic System Optimizer optimizations

DSO extends the function of the ASO with additional optimization capabilities.

Cache and memory affinity optimizations
The cache and memory affinity optimizations are functions of the AIX Dynamic System Optimizer that change the settings by minimizing the amount of data that crosses the affinity domains.
Large page optimization
Large page optimization is a feature of IBM® AIX Dynamic System Optimizer that automatically changes the page size to a larger 16 MB page size when it predicts improved performance.
Data stream prefetch optimization
The data stream prefetch optimization is available only in POWER7 processors. The data stream prefetch optimization is a feature of the IBMAIX Dynamic System Optimizer that modifies the Data Stream Control Register (DSCR), when required, to improve the performance of an application.
