Performance marker used for profiling arbitrary code blocks.

Use ProfilerMarker to mark up script code blocks for the Profiler.
The information produced by markers is displayed in the CPU Profiler and can be also captured with Recorder. During development (in Editor and Development Players) this can help to get performance overview of different parts of game code and identify performance issues.

using Unity.Profiling;

public class MySystemClass { static ProfilerMarker s_PreparePerfMarker = new ProfilerMarker("MySystem.Prepare"); static ProfilerMarker s_SimulatePerfMarker = new ProfilerMarker("MySystem.Simulate");

public void UpdateLogic() { s_PreparePerfMarker.Begin(); // ... s_PreparePerfMarker.End();

using (s_SimulatePerfMarker.Auto()) { // ... } } }

ProfilerMarker represents a named profiler handle and is the most efficient way of profiling your code. It can be used in jobified code.
Methods Begin and End are marked with ConditionalAttribute. They are conditionally compiled away and thus have zero overhead in non-Developmenet (Release) builds.

When Profiler collects instrumentation data, ProfilerMarker helps to reduce overhead and the amount of transferred data. Profiler.BeginSample transfers full string to the data stream while ProfilerMarker.Begin and CustomSampler.Begin only integer identifier of the marker.

Also ProfilerMarker.End provides a context information to the Recorder making it possible to track timings of a marked code in Players.
