What if I've analyzed how much ram I need, and ensued that I have "enough" ram in my production system and don't have to worry about needing more. I'll know when I need more when my monitoring metrics tell me I'm getting low, or if I't monitroing, when the server hard fails because it can't allocate ram. I prefer that situation than a gradual degradation eating into swap. Ram is cheap.
