Hi Michael, Is this LLVM+Clang? Just LLVM in 75 minutes is quite a lot, even for a Tegra3. For distcc, you really want to use ninja pools: http://www.systemcall.org/blog/2013/02/distributed-compilation-on-a-pandaboard-cluster/ It'll speed up your linking and reduce the memory footprint. What I really wanted was that distcc would know the linking dependencies during compilation and compile the same groups on the same boards, so that linking could *also* happen on a distributed fashion, but I'm not considering implementing that myself. ;) About the pump-mode slow-down, I think it was the network, that was done over Wifi due to limitations on the office network, but I'm not sure. cheers, --renato
