Did you test on a "real" FreeBSD & Linux hardware (not VMWare)? Because
VMWare **greatly** pessimizes low-level operations that depend on
atomic/bus locks, CMPXCHG & similar operations that are used in
synchronization, context switches & multithreading, and IO operations
are also very very slow compared to real hardware. It simply cannot be
used to do benchmarks on (except if you're benchmarking vmware, not the
guest system :) )
