Property Name - Performance Impact?

If one uses property names with no space, the property can be referenced without using GetProperty.

Example: If(Air_Mission==3, 0 ,1)

If using spaces in the name one must use the GetProperty function.

Example: If(GetProperty(“Air Mission”)==3, 0, 1)

My question: In a large, complex module with very many properties defined, is there a performance toll to use the GetProperty function? Would there be a performance improvement in the module if GetProperty use is minimized?
