http://wiki.freebsd.org/DefaultDebuggingKnobs I am not aware of any linux distribution that comes with debug enabled = by default, even on RC releases. It seems that this approach (debug by default) is welcome to help solve = problems that might appear, but I would be happy if these benchmarks = were made without such config (debug) enabled.
