A Look Into NUMA, Hardware, Linux & Oracle Performance
Frits Hoogland, Accenture Enkitec
The majority of the Oracle database servers uses two CPU sockets nowadays, however the trend of increasing the amount of CPU rather than making the CPU faster has started quite some time ago. In today's common hardware architecture, memory is local to the CPU socket. This means that an understanding of the implication of memory locality is imperative to computing performance.
