Run profiling
You can start profiling in several ways. All options run your application with the Go profiler.
Run profiling
To run profiling, do one of the following:
Open the run configuration selector on the toolbar, click the More icon, and select Profile with Go Profiler.
Open a file that contains a
mainfunction or a test, click the Run icon (
) in the gutter, and select Profile with Go Profiler.
Open the Go Performance Optimization tool window, select a configuration in the Profiling with pprof tab, and click Run with Profiler.
Use the Go Performance Optimization tool window
The Go Performance Optimization tool window provides a central place to run profiling and manage profiling sessions.
Tool window overview
The tool window contains sections to start profiling and to manage results.
Configuration selector lets you choose a run configuration.
Run with Profiler starts profiling for the selected configuration.
Running processes shows active profiling sessions.
Recent profiles lists saved profiling results.
Work with profiling sessions
After you run profiling, GoLand stores the results as profiling sessions.
View and open profiles
Use the Recent profiles section in the tool window to access recorded sessions.
Click a profile to open it in the profiler view.
Remove profiles
To remove a profile, use the context menu in the Recent profiles section.
Import profiles
You can import profiling data that was collected outside the IDE.
Import a profile
In the Go Performance Optimization tool window, click Import Profile.
Select a profiling file.
Open the imported profile from the Recent profiles section.
How profiling runs
When you start profiling, GoLand builds and runs your application with profiling enabled.
The IDE uses a temporary build configuration and does not modify your source files.
