Memory Settings in SmartPLS 4

Usually you do not need to change anything: SmartPLS 4 uses the memory that is available on your computer. A fixed limit in the configuration file is rarely needed.

Where the setting is

The limit is set in a configuration file:

Windows: C:\Program Files\SmartPLS 4\smartpls.vmoptions
macOS: /Applications/SmartPLS 4/smartpls.app/Contents/vmoptions.txt. In Finder, right-click the app, choose Show Package Contents and open Contents/vmoptions.txt.

You need administrator rights to change this file.

Set a fixed limit

Open the configuration file in a text editor. On Windows, start the editor as an administrator (see the screenshot below), otherwise you cannot save the file.
Find the line that starts with -Xmx (the number after it is the limit in MB, for example -Xmx2048m).
Change the number. Stay well below the main memory of your computer, so the operating system keeps enough.
Save the file and close the editor.
Restart SmartPLS to apply the limit.
