Optimize KeyCreator Performance
When Working on large file on KeyCreator, You may encounter out of memory errors. This can be overcome by tweaking MS Windows Memory setting:
Boot.ini
/3GB Switch
/PAE
/USERVA=2500
Virtual Memory
It is suggested to set the virtual memory 3 times the size of the physical memory (Also known as RAM), therefore IF your computer has 2GB of RAM (~2048MB), it's recommended to set the virtual memory size to 6GB (6000MB)
