Looking at (gnu packages rust), the mrustc-based bootstrap starts with 1.54.0. This one is expensive, probably around 1 h 30 or more on a Ryzen 3900x CPU (24 logical CPUs). The intermediate builds are typically around 15-20 minutes on that machines, with the last one taking a bit more (30 minutes), so the current bootstrap on such a machine should take about: 1.54.0: 1h30m 1.55.0 - 1.60.0: 6 X 20 min =3D 1h20m 1.60.0: final build with tests and extra tools: 30 min The total should be around 3 h 20 on a fast modern x86_64 machine. I suppose the time for berlin to build it takes about this. HTH! --=20 Thanks, Maxim
