Yeah but if you exceed the treshhold it would start swapping to scratch disks automatically so you'll kill your performance. You said in the test to limit the amount of RAM in increment of 4GB and see how it behaves. My guess is that it'll swap to drive (earlier) automatically depending on how much RAM the shot you've run the action on is using initially. So whether you have 8GB or 24GB of RAM if your carboni action chews up 6Gb let's say then the result will be the same because you're still within the RAM quota allocated.
