First some data:
MBA 4,2 with a 240gb SSD.
amount of RAM installed is a big factor; my guess is yours has 4GB
More browsing, playing some video through Airplay to an ATV
Left on overnight (meaning no reboot)
11:00 am =39.81 GB
something is chewing up swap at an unusual rate; use top or Activity Monitor to
sort processes by VPRVT, you may find a culprit; if it looks like Safari or
Chrome is doing it, i'd suspect some pages have large JavaScript apps running
in them; with Chrome, as we have been discussing, the Task Manager lets you
probe usage per tab (and per extension)
The questions:
If the swap file size is dynamic, shouldn't it shrink when I quit out of
applications?
it will in many cases, but generally not in exact proportion to how much swap
an app has caused to be added; some is "stuck" because, for example, different
apps have both mapped memory to locations within the same swap file; it can
take a while (minutes) to release what may be released
Is anyone else seeing this kind of SWAP accumulation? Aye Yi Yi
i have seen it near that high, though i bet i push my machine a lot harder; i
also have 16GB of RAM, which essentially means 12GB more RAM must be consumed
before i reach the same amount of swap
