Sorry to be dense here, but what is the problem with that output?
That there is a lot of memory marked as "free"?  Why would it mark
any memory free?

That's kind of my point. :) That 14GB isn't allocated to cache, buffers, any process, or anything else. It's just... free. In the middle of the day, where 800 PG threads are pulling 7000TPS on average. Based on that scenario, I'd like to think it would cache pretty aggressively, but instead, it's just leaving 14GB around to do absolutely nothing.

It makes me sad. :(
