: I'm running at 40 at the moment on this box with 1.5GB of RAM that
:used to hardly touch swap but these days is often to be seen with 300Mb of
:swap in use and 800Mb of inactive. I think I'd rather see the swap usage go
:away and the inactive queue shorter. Adding up the vsz of all the processes
:running gets me to about 1GB. It would be nice not to be using swap again.
: Raising the setting to 40 seems to have increased total swap usage
:at the same time as reducing the tendency for things I use to be swapped
:out in the morning - this puzzles me somewhat.

You can change the VM paging targets. You can try reducing
vm.stats.vm.v_inactive_target. Those values are in pages. Do
not make it too small.
