Hello Ralph,

"Notebook History Tracking" only affects what is saved with the notebook 
you are working with, but it does not affect how the kernel works or 
what it keeps in memory (i.e. doesn't appreciably affect memory use). 
This option will simply record the times at which who have created or 
edited each cell.  If you open a notebook file with a text editor, 
you'll see this information in the CellChangeTimes options.

Turning it off will slightly reduce notebook sizes and makes version 
tracking much more convenient.
