Is CLANG/LLVM expected to perform better ? How much is due to FreeBSD using an older Xorg ? (or is this not relevant to the benchmarks ?). A recent Phoronix article showed that Ubuntu 9.04 (I think) performed worse than Windows (7 I think) using the same open source software. Interestingly though, Windows binaries generally ran faster under Ubuntu using Wine than they did under Windows. This makes one think that GCC still has a long way to go compared to MS Visual Studio (or Wine has a lot less overhead than a full Windows system). Matthew
