What system resources does Spaces use?

[VirtualRain]

Is Spaces actually creating a larger virtual desktop or is it just a single desktop and hiding/showing apps based on the selected space?

What resources are being consumed, if anything, by adding spaces? Main memory? Video ram? Nothing?

Does anyone here run a large number of spaces? eg. 9 or more? Does it slow down your system?

It does not make virtual desktops and very little to no resources
