Description
In R1beta2 I've noticed excessive amount of swap usage even when very little RAM is used.
I have attached a screenshot from running on a machine with 16GiB RAM.

I've seen this too. mmlr, any ideas?
Yes: It's just a misleading counter that is being shown. The number that is shown is not the actually used swap space, but the amount of memory that has been reserved in swap to guarantee backing for application allocations.
Given a large enough swap file you'll usually see roughly the amount of used memory reported under swap after boot. This includes most normal area allocations, minus things like stacks that are overcommitting and explicitly overcommitting or wired areas.
This should simply be changed so that it actually shows the swap space in use. Incidentally I made such a change locally just yesterday and will test and push it sometime soon.
