See http://www.nedprod.com/Tn/ (scroll down to the > screenshots). 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 :) )
