This paper introduced a much more precise sampling method using CPU hardware performance counters (CHPC) to provide CPU data like instruction cycles, cache misses, branch prediction, and so on, and given detail scene of software status.

• 摘要引入了基于CPU硬件性能计数器的性能数据采集和分析方法，从软件运行时刻的细粒度参数入手分析软件运行时刻的性能表现，从而更为准确地反映系统实际的动态运行状态。
