OK, you were right: atlas took 115m37s, i.e. about 2hrs . When you say cache size, do you mean on the machine? The laptop has 2GB ram -- was supposed to have 4 but they forgot to install it and I am expecting a guy to come by in the next couple of days to install the extra. But maybe that is not what you meant.
