Makes sense, DragonflyBSD uses GCC 4.7 as its default compiler and last time I checked it had better OpenMP support than GCC 4.2.1 which is what FreeBSD defaults to at the moment.
Perhaps when Clang gets OpenMP support and they release FreeBSD 10 (with Clang as the default compiler) there might be change but for the time being, it just lacks those extra optimisation hooks that DfBSD has.

I don't think any of those benchmarks require openmp.
