On my 12 core system, build time for qemux86 from scratch is ~42 minutes. This compares favourably with previous numbers from that system. Interestingly, switching to qemumips resulted in a build time of 43 minutes in the same tmpdir suggesting that the native part of the bootstrap process isn't the bottleneck. On the quad core (the system used for many of the previous numbers I'd provided), build time for qemux86 was 105 minutes which again is roughly consistent with where things were for 1.1. So things haven't changed much recently which is as I'd expect. We haven't seen many performance related patches but its good to know things aren't regressing either. Cheers, Richard
