I would like to thank very much everybody taking part in discussion. Does an answer above suggest that I can open two R console and do simulations simultaneously? If so, all simulations take more or less 1/2 times - or much less then doing it in turn?

During our discussion one mentioned that RAM is important. But in my computing I do not use up more then 500 MB. I have 786 MB it means (probably) that I have enough.
Am I right?

Best,
Rob
