Changing Sunflower's Memory Setting
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. _section-memory-setting:

Sometimes it is useful to increase the memory allocation for **Sunflower**, especially when dealing with large .flr files or KB.  A larger memory allocation will yield better **Sunflower** performance.

If **Sunflower** is running, exit it before changing its memory setting.

To change memory allocation for **Sunflower**, edit the Sunflower Studio CE.ini file.  On Windows, this file can be found in the **Sunflower** installation folder.  On the Mac, this file is in the folder Sunflower Studio CE.app/Contents/MacOS.


In Sunflower Studio CE.ini, the 2 lines immediately following -vmargs specify the minimum and maximum memory allocations for **Sunflower**.  To increase the maximum amount of memory allocated, change the line which has -Xmx, as shown in :numref:`figure-sunflower-ini-file.png`.  For example, change it from -Xmx2g to -Xmx3g, and save the file.  Next time **Sunflower** runs, this new setting will take effect and allow a maximum of 3GB of memory instead of the default 2GB.
