You should use the oldest CPUTYPE that any machine that will use those packages has. If the host does not support core2, don't use it, use some older one. Also, if it does not support it, bhyve won't work there as it is too old. (As a rule of the thumb, don't use CPUTYPE, at best you will win a few cycles here and there, but it will more generally be more painful when you discover you need to use the packages some place where that CPUTYPE is to recent.) -- Mathieu Arnold
