Yes, but that's using a single core, which I'd never be doing on a machine like the one described - running -j8 sounds perfectly reasonable. However, it occurs to me that when I said 5 minutes, that would have excluded tests, since my automated builds skip them. Can't remember how effectively those can be parallelized, but I'd still not expect even the Chapter 6 gcc build to take more than 20 minutes... Simon.
