I think you missed the point.  I'm saying *if* you *have* to change swap 
frequently, then there is an advantage to having swap on LVM.  But, if you 
had read the rest of my message (I don't know either way, but you did take 
the quoted paragraph out of context with the next one), then you would have 
read me making basically the same point as this:

Right.  Like I said, if you're hitting swap, performance is going to suck and 
at that point, every little bit helps.  If you find that you're always in 
swap, then you need to reevaluate the RAM, storage and/or activities on the 
machine(s) in question.

A dedicated swap drive is less hassle and better performance than LVM swap, 
*if* you *need* that kind of swap performance.

I like the way you phrased it here: "...swap is more a security feature than a 
normal-use-feature...", though I might replace the word "security" 
with "safety" or "safety net".
