look at swap cached in /proc/meminfo that will tell you what is
mirrored.
Also, your box may not be actually doing much swapping if any at all. vmstat
will tell if you're actually doing any swapping at a given time.
Allocation may carry over to swap, but it doesn't effect performance in any
way in doing so. That's why looking at anything but vmstat really wont tell
you much about what's actually being used in swap.
