I have noticed swap being used considerably more with the latest kernel -- has anyone else seen this?
For example, my main desktop system was sitting idle all night, in init 5, with only KDM running. The first thing this morning I checked memory, and saw this:
don@imerabox:~$ free
total used free shared buffers cached
Mem: 6109312 2539192 3570120 0 103376 1493612
-/+ buffers/cache: 942204 5167108
Swap: 15114748 234672 14880076
Yesterday, I noticed when I was running a VM that it was actively swapping a little bit -- this was vmware. I have not ever seen that before, with a single VM running. I have vm.swappiness set lower than default -- to 1, because I have more memory than would normally be needed.
Just curious -- has anyone else observed an increase in swapping?

Definitely yes.

Here is my memory with 2 browsers, 1 music player, and 1 VM running:
don@imerabox:~$ free
total used free shared buffers cached
Mem: 6109312 5996840 112472 0 588 3363896
-/+ buffers/cache: 2632356 3476956
Swap: 15114748 1261412 13853336
This is way more memory than normally gets used on this system.

Current state of my memory: I have icedove, Gimp (1 picture) and chromium (7 tabs) running. Used RAM is 59% of 3959 MiB and used swap is 30% of 2047 MiB. There is enough RAM available so why all the swapping? I'd expect swap only to be used as a fill-in when RAM is totally filled.

With the new kernel 3.8-3, this situation has dramatically improved. Here are my conkys from yesterday (3.8-2) and today (3.8-3):
