The speed of the random number generator vs importing a text file?

From: PauliePorsche on 11 Aug 2010 16:52 I have to run lengthy simulations which involves generating numbers randomly literally millions of times. I ended up running this simulation, figured out I'll need to tweak some algos, and re-run the simulation My question is it quicker to import a text file (from the previous simulation) and use the random numbers from that than it is to use the random no# simulator?

Reading a text file is very slow in comparison to any simple ops like generation of random numbers. John
