Collect performance data about the Unity Editor

Profile the Unity Editor process to understand the performance of the Editor itself or how the Editor process affects your application in Play mode.

To profile the Editor:

1. Open the Profiler (Window > Analysis > Profiler)
2. Select the Target Selection dropdown, next to Record
3. Select Edit

When Editor profiling is enabled every Profiler frame corresponds to one Editor tick which is represented by the Application.Tick sample. However, during Play mode profiling, the Profiler aligns its frames with a player frame, so that you can inspect the composition of EditorLoop markers and compare Play mode frames with or without Editor profiling enabled.

Tip: To reduce the impact that the Profiler window has on Editor performance, open the Profiler window in its own process with the Standalone Profiler. The Standalone Profiler is useful because the Profiler window itself uses resources that might skew the performance data.

Profile the Editor’s startup times

To profile the Editor’s startup times, start the Editor with the command line option -profiler-enable. Refer to Profiler command line arguments for more information.
