my test methodology is practical workload and not constructed crap
i profile my own web-applications which are highly optimized

believe it or not, they are faster in a VMware guest as on the host
itself in many cases, both the same Fedora version with binary
identical packages optimized for corei7 and SSE4.2

-O3 -march=corei7 -mtune=corei7 -mmmx -msse2 -msse3 -msse4.1 -msse4.2 -maes -fopenmp -mfpmath=sse
