Are you interested in better understanding memory access performance? A new article, Unta
This article takes a practical approach to measuring memory latency performance, from understanding initial results to moving on to examining the effects of more in-depth system settings and tunings. The article also covers details of the underlying memory hierarchy on POWER7+ systems, so that you have an understanding of the system layout and how the processors interact with memory.
