Good performance is crucial to many applications. Program performance tuning is a multifaceted
activity grounded in measurement and analysis. Measurement provides an objective basis for
assessment and comparison of the performance aspects of program design and implementation.
AMD processors offer extensive features to enable performance measurement. These features
use hardware counters to measure performance-related events caused by user- or kernel-level
software. Event counts help a systems engineer or software developer to identify the likely cause
of a performance issue.
