Virtual memory will slow down the program by several orders of magnitude. Just make your hash tables too big, and you will find out why. If a disk has an access time of ten milliseconds [we'll pretend the read/transfer is instantaneous], and memory has a speed of 100 nanoseconds, that's 10*10e-3 = 1e-2 sec disk 100*10e-9 = 1e-7 sec ram Ram would be (roughly) ten thousand times faster. I'm not sure about 95/98/00, but under NT, I can allocated 500+ megs of ram and I only have 128 megs of physical ram on my machine. But to loop through that array would take a loooooong time. In short, what you wish for is not what you wish for.
