  I'll change that, and also change the simple rule to give the reader a
straight answer.

  Well, all in all, i don't think so. Is there a reason to think
otherwise ? If you have enough ram, linux will swap out pages if it
thinks this will decrease overall disk access (increasing the amount of
available cached memory). Maybe i'm wrong ?

  I'm not sure about that. first partitions are said to be faster, but
i'm not sure about the effects for the entire system. Also, setting the
swap as the last partition may help changing your partition scheme (it's
often possible to extend a partition but not to move it) ...

  Yeah, i thought about that, i'll include these cases in the faq.

  Thanks :)
