# Performance analysis

Performance analysis involves assessing app behavior, resource utilization, and responsiveness.
Examine app threads scheduling, memory behavior, and frequency scaling to identify bottlenecks, inefficiencies, and areas for improvement.

This section describes the following:

- [Workload characterization](https://docs.qualcomm.com/doc/80-62010-1/topic/workload-characterization.html#workload-characterization): How to identify which subsystem (CPU, GPU, NPU, etc.) an application is bound to.
- [Scheduling issues](https://docs.qualcomm.com/doc/80-62010-1/topic/scheduling-issues.html#scheduling-issues): How to use [Windows Performance Analyzer (WPA)](https://learn.microsoft.com/en-us/windows-hardware/test/wpt/windows-performance-analyzer) ![devhw](data:image/png;base64,UklGRt4AAABXRUJQVlA4TNIAAAAvD8ADED/BoG0jSe5SXP5I7gkNRG3byLnX4Tn+2K4I2raNw5/iqPxlEwBAGlwuj8BNBPpnsblrANx3P36s+DHQIcQ0dmEfEGPc8WEcCCcO/M2hXv3rDJTcHCTB1es7l9P2UoywA2a3jSW/pp77EhxGkq1E8zjH3R3e/fxjREOI6P8EcH+lqu/oTK/6kS+YwlHVAMjkP0ErP1UNIZZmnsB32Y2lZjNPO7HUUA1HkVWz73lAIiWM6WaegFcHzNOJ3bv89WhdNu1TDx/txhT2np2bzWU=) to verify cluster usage and to verify that frequency scaling is happening as expected.
