To set the Maximum Java Heap memory FRP can use to run you can alter the value found in the file javaLauncher.properties and is part of the App bundle under Contents/MacOS.
for eg: ${installdir}/FRPRep.app/Contents/MacOS/javaLauncher.properties
The default value is 1600m or 1.6GB. The value can be as low as 512m for machines with little work and few FRP jobs, for machines with huge numbers of files, folders, and more than several jobs the value may be higher. This memory is reserved from PHYSICAL RAM memory on an as needed basis up to the limit you set here, it's released when not needed. You can experiment with these values and adjust as needed. A restart of the FRPRep.app will be required to make changes take effect.
