→Algorithm Optimization
The user-mode sampling method will only gather data relating to your application and not the wider system performance. The results will show total time usage of functions within the application. If many samples are collected during a specific process or thread, we can identify these as hotspots and potential bottlenecks in the performance of the application.
==== Hardware Event-Based Sampling ====
Event-Based sampling is based more on hardware events. It utilizes the hardware events to collect data on all the processes running on your CPU for a given moment and provides analysis for performance of the whole system. Similar to the user-mode sampling the profiler generates a list of the functions being used in your application and the time spent for each of them. By default the event-based sampling mode does not collects stacks like user-mode sampling, but you can choose to turn that option on.
