Efficient Instrumentation for Performance Profiling

الأصل · EN

Performance profiling consists of tracing a software system during execution and then analyzing the obtained traces. However, traces themselves affect the performance of the system distorting its execution. Therefore, there is a need to minimize the effect of the tracing on the underlying system's performance. To achieve this, the trace set needs to be optimized according to the performance profiling problem being solved. Our position is that such minimization can be achieved only by adding the software trace design and implementation to the overall software development process. In such a process, the performance analyst supplies the knowledge of performance measurement requirements, while the software developer supplies the knowledge of the software. Both of these are needed for an optimal trace placement.
