How can I use more memory??

By default, SmartPLS uses a maximum memory of 2048 MB. If you perform extensive calculations, you may need to allocate more memory. You can check your SmartPLS 4 memory consumption under the menu item -> SmartPLS -> Memory consumption.

If your computer has enough main memory, you can allocate more memory to SmartPLS 4 for its calculations. This can significantly increase performance. To allocate more memory, you need to modify the smartpls.vmoptions configuration file, which can be found here:

Windows: c:/program files/SmartPLS 4 MacOSX: /Applications/SmartPLS 4/Contents/ Note: On Mac OSX you need to select smartpls in the above mentioned folder and use the "Show Package Contents" options.

Then open the smartpls.vmoptions file in a text editor and change this line


for example into, for example,


Instead of 4096, you can also choose a higher numerical value. This value should not exceed the main memory actually available on your computer. If your computer has 8 GB of RAM (i.e., 8192 MB of RAM), you should select the -Xmx4096m entry to allow the SmartPLS 4 software to use a maximum of 4096 MB of memory.

After you have saved your changes, restart the SmartPLS software.

Note: You must have administrator rights on your computer to modify the smartpls.vmoptions file. If you cannot save it, try to open the text editor as an administrator. Another option is to copy the smartpls.ini file to the desktop, edit and save it there, and then copy it back to the original folder. Windows will ask for the administrator account when you copy the smartpls.vmoptions file back.
