pp: 68-71
ABSTRACT
CPUs spend most of their time waiting for data to arrive. Identifying low-level bottlenecks—and how to ameliorate them—can save hours of frustration over poor performance in apparently well-written programs.
INDEX TERMS
keywords: CPU performance, processor speed, memory speed, I/O bottleneck, multlicore computing
