But in case the pagefile is on a virtual RAM drive, the time used to copy some megabytes from RAM to virtual hard drive or back from it will be reduced. And if the pagefile is disabled completely, there should be no time wasted on that at all. Is this correct?

Correct. Copying bytes from RAM to a pagefile that is on a ramdisk is the fastest possible pagefile. But not copying at all is smarter.

Swapfiles are there to compensate for a lack of RAM. If there's plenty of RAM, there's no need to compensate. Your OS will still use the swapfile though, so it's quicker to turn it off in that case.

@Mast That's a gross oversimplification. Swapfiles are also there to permit efficient use of RAM.

@DavidSchwartz Perhaps, but that's the explanation that explained it to me the best. In most cases, a small amount of swapfile is always benificiary over no swapfile. However, I don't have the resources to back that up.
