:-(
As normal, while looking at one thing, something else bites my butt. I
tuned on the swap field in top and sort on it. Here's an edited snippet
of the results.
Mem: 775708k total, 764752k used, 10956k free, 60780k buffers

Note that the summary line says 160k of swap is used. The man pages say
the summary and the details under "SWAP" are both reported in "k". No
mention of "m" is made, I presume that it means "megabytes"?
If so, I can't reconcile what I'm seeing. Free seems to support the
summary lines.
total used free...
Mem: 775708 764772 10936...
-/+ buffers/cache: 326584 449124
Swap: 1572856 160 1572696
Cat of /proc/meminfo also seems to support the summary lines.
SwapTotal: 1572856 kB
SwapFree: 1572696 kB
Looked at the same top info, and I don't understand what I see either.
With processes running, I'm seeing close to 500mb of stuff swapped out,
but according to free, only the 2.2 mb is swapped. There's gotta be
more to this than meets the eye, or something is lying about the swap.
The system monitor also shows only 2.2mb of swap in use, so where is top
getting this 500+ mb of swap data from?
most of the 'swapped' data is probably sitting in the cache or buffers?
Here is an example:
