Profiling is a process that calculates how much time and resources are used to complete certain processes. It is useful for finding inefficiencies in code that slow down productivity. The Profiler allows you to locate performance bottlenecks in your scene by recording and demonstrating in a graph the amount of time that each process consumes.
The Main category is always recorded regardless of its setting in the Record/View Categories window. If you disable this category in the Record/View Categories window, its events are considered hidden and included in the Hidden events count at the bottom of the Profiler.
Streamlining your view and recordings reduces clutter in the draw region and simplifies the visualization of data.
The Profiler now illustrates a graph demonstrating the processing time for your animation.
See Interpret your Profiler graph results for information on how to interpret your Profiler graph.
