I think it's hard to say, as there are time-consuming tuning procedures ran by NTL (and if you build Atlas, its tuning may take really long). Building gcc is a bottleneck too, so if you avoid it you get quite a speedup. It also depends on the kind of harddisk used (SSD or the "classical" drive, etc), as a lot of building time is reading/writing to disk. The type of filesystem you use would also play a role. On an old Apple laptop (late 2010 AirBook with Core2 Duo CPU) with a similar CPU, only 2-core, not 4-core, building Sage was always very slow, taking a good part of the day. (Faster with Linux than with OSX, although not by much). > > Martin > > Am Montag, 17.
