I build on Linux and those build times seem fast to me (20-30 seconds, 45-60 seconds). I don't know if I've ever had builds that fast, but it might be my configurations, or my machine. I'll build one now... Latest master: 1m 47s Let me get an older revision... 1m 50s to build with bb10e0fc25a1c6006e8ad2724be29173d4858494 which is before the commit mentioned by the OP. These build times are pretty consistent with what they've always been for me, approximately 2 minutes for a complete build. So, at least so far, I don't see a change... Nathan
