unused objects are removed from memory and memory allocation is disabled until you restart the project.

Performance control has default settings that should work for most projects running on most clients, but
if you have problems, then you can adjust the settings for your project or even disable memory allocation
altogether.
To configure the performance control settings:
1. On the Project tab of the ribbon, in the Settings group, click Options.
The Project Settings dialog box is displayed, with the Options tab selected.
2. In the Options tab, in the Performance Control area, click Configure.
The Performance Control dialog box is displayed.

the Before disabling allocation box.
