Performance tuning tips

Enable memory indicator

To determine whether performance issues are caused by low heap memory, enable the memory indicator:

• Right-click the status bar and select Memory Indicator.

The memory indicator will appear in the bottom-right corner:

Increase memory heap

1. Select Help | Change Memory Settings from the main menu.

2. In the dialog that opens, set a higher memory heap value in the Maximum Heap Size field.

3. Click Save and Restart.

Adjust -Xmx

To increase the memory heap, you can change the -Xmx option, which sets the maximum heap size for the JVM:

1. In the main menu, go to Help | Edit Custom VM Options. This action creates a copy of the .vmoptions file in the IDE configuration directory and opens it in the editor.

2. Update the -Xmx value. For example, use -Xmx4096m to allocate 4 GB of memory instead of the default 2 GB.

3. Restart GoLand to apply the changes.

   

Enable Power Save mode

You can enable Power Save Mode or battery efficiency mode using one of the following options:

• As an alternative to disabling individual checks or files one by one, try using Power Save Mode. This mode disables all inspections and other resource-intensive background tasks across the entire IDE.

  To enable Power Save Mode, go to File | Power Save Mode.

  

• Right-click the status bar and select Power Save Mode. The Power Save Mode icon will appear on the status bar.

  

Exclude directories and file types

• Your project may include folders with binaries, logs, or build artifacts that do not affect GoLand code insight. Indexing such folders can also be resource-intensive due to their size or location. In these cases, it is reasonable to exclude the folders manually: right-click the directory in the project tree and select Mark Directory as | Excluded.

  Once files are excluded, their symbols are no longer available to GoLand. The following features will be disabled for excluded files: code completion, auto-import, code generation, Find in Files (except in open files), navigation, and refactoring.

• You can also exclude files such as logs or generated data by file type. To do so, go to Settings | Editor | File Types and add the pattern to the list of ignored file types:
