The tried and true of thousands of IT Pro's not withstanding...
You would THINK that your right, that would logically seem the case if you didn't know the intimate internals of Windows of nearly all versions.
95, 98, NT, I know would try and allocate 4 GIG of memory space for creating the protected virtual systems for the applications. (way oversimplification) How much it used was an entirely 'nother matter. It's been nearly a decade since I stopped wasting my money on certifications, and haven't kept up on ME, XP, or 2K. Hence, my ability to render a suffiecient understanding is lacking.
As a general rule, for stability and such, It has been recommended by Industry leaders and review websites across the board, that the swap file be set at double the Ram. if you noticed, I mentioned on Fast 98 systems you can turn it off completly if your above 512, to absolve certain performance issues caused by the computer saving to the swap space. But this was usually reserved for production of multi-track talk show editing, where the pause was perceptable. In graphic editing, it is only noticed during the editing, and not as a final product. I am sure you can appreciate the difference here.
