I'm not saying it's not important. It's that I don't have any control over it. Do I have enough "cache" in your opinion? Presently I have: Used: 14.6 Avail: 16.6 Cache: 4.2 Free: 6.4

If I'm asking the question "Is my system starved of RAM?" I am going to look at USED and AVAIL. CACHE is a curiosity more than anything else and FREE tells me nothing.

Also, under what circumstances would I have a ton of AVAIL and be starving the CACHE? That's an OS/kernel problem. If AVAIL drops to zero I can expect to get OOM crashing pretty quick.
