I don't think you can validly conclude much from just one sample of each
type. Try repeating those tests enough that you can do some decent
statistics.
Oh, and you should probably either discard the first few results, or
else take pains to flush[*] the buffer cache between each run, so you
end up measuring the same thing repeatably.
Cheers,
Matthew
[*] Unmount and remount /usr/ports should do that I believe.
