That isn't what it is saying at all.
If cache/buffers (the relevant output of which you deleted) were not in use, that's how much extra
free memory you'd have. As your applications are not
demanding it, it's used more productively.
Would you rather you'd paid for that 12 Gig and never use it ???.
Same for the swap usage. Long term idle anonymous memory pages are pushed out so the RAM they occupy can be used elsewhere.
What's your uptime ???.
(In future use code tags to make your data readable)
D'oh - left out the emphasised "not" above.
