Profiler Fundamentals

For samples, the profiler stops the execution of the profiled code at a fixed rate, for example, every 1ms and records relevant information like the current stack. These samples are aggregated together and provide a statistical look into the execution of the program. There is no guarantee that all of the code that is running will be sampled, but with enough samples, it provides a good look into where time was spent while running the targeted code.
