Every issue can be delt with, in some way. If you'd like to fix the
relationship between the kernel so that mismatched worlds and kernels
aren't always terrible, feel free.

What is "it"? I'm not too sure what you are referring to.

FreeBSD is portable, thank you. The bootsector followed by device
drivers is the problem, because not many people are interested in
the non-x86 side of FreeBSD, but the OS itself _is_ portable.
As for speed, that depends on the application. AFAIK Linux still
lacks any form of preemptive swapping in the VM subsystem. Result: when
your demand for memory exceeds the physical RAM, your inactive pages must
swap out as soon as the newer process requests them, with a result of
heavy I/O when you first start swapping.
