===Performance Snapshot===
This feature will take all the different types of analysis and provide you a summary of each analysis and show how the performance is for each one, while highlighting the ones with the worst performances. This allows users to easily pinpoint which sections need to be prioritized and which sections may require more time to resolve.

====Hotspots====
This feature will User-Mode Sampling or Hardware Event Based Sampling to collect data while your application is running. After the data collection is completed, it will display where in the process does the code stall or take the most time running and how well you’re utilizing your CPU threads.

You can also open the source code and display which functions are taking up the most CPU time. Which allows you to pinpoint where you should start on optimizing your code and allows you to focus on the functions that are causing the most run-time delay.

=====User-Mode Sampling=====
VTune uses a low overhead (~5%) sampling and tracing collection that works to get the information needed without slowing down the application significantly. The data collector uses the OS timer to profile the application, collects samples of all active instruction addresses in intervals of 10ms, and captures a call sequence. Once everything has been collected, it will display the results of the data collection in the results tab.
=====Hardware Event-Based Sampling======
VTune will analyze not just the application running, but all processes running on your system at the moment of run-time and will provide CPU run time performance on the system as a whole. It will still create a list of functions that run in the current application while timing them, but it won't capture the call sequences as hotspots.
