you don't understand, that would be a silly and pointless thing to do. first of all, vm has considerable overhead and if implemented in ram would effectively make the ram slower. the idea behind virtual memory is to effectively give you more ram, at the expense of speed. the idea behind setting up a ram disk is to give up some of your ram and use it as a faster hard drive. by comparison, vm is like over draft protection that transfers money from savings to checking when necessary, a ram disk is like manually moving money from savings into checking to make it more effective. so what you want to do is move all of your money to savings, and then overdraft protect it right back into checking accomplishing nothing but wasting time and money. setting up a ram disk removes memory from normal use as ram and makes it emulate disk access with substantial housekeeping overhead, setting up vm (on a real hard drive) allows you to pretend you have more ram at the expense of speed and losing the use of some drive space for "normal" file storage. it's sort of like taking all of your money, buying a house with cash, and then borrowing on the houses equity and putting that money back into your hands as cash, you get to pay interest that way, and in this anology, you wouldn't be able to live in any part of the house with a loan against it so you've accomplished nothing beyond a great big time and effort waste. what you are suggesting is basically the same thing, there's no logical reason to do it, even if you could you'd just be shooting yourself in the foot.

White House Press Secretary Ari Fleischer. If giving up freedoms makes you feel more secure, I suggest you move to China and tell me if it really makes you feel safer, but don't ask me to give up what so many died for. Be polite, respond OFF LIST if you "simply" must. --End Signature Block-- Begin forwarded message: > From: [EMAIL PROTECTED] > Date: Fri Feb 14, 2003 11:46:46 PM America/Denver > To: <[EMAIL PROTECTED]> (G-List) > Subject: Re: RAM Disk as scratch disk > Reply-To: <[EMAIL PROTECTED]> (G-List) > > If I used a RAM disk as a scratch disk, then I could do what I > please > with my memory.
