Linux Performance Analysis With Perf
Tuning systems and applications for speed requires tools to gain visibility into the performance hotspots that will yield the largest improvements. Perf, which we cover in this tutorial, constitutes one of the latest additions to the Linux world in the field of performance analysis. As an built-in performance profiler, perf lets us easily gain access to various performance counters and metrics needed to optimize software performance under Linux. In this presentation we briefly expose some of the strategies and techniques used in high performance environments and discussed at length in our Linux Advanced Performance Tuning class.
