And you're concerned with memory usage? LOL Why do you have 20GB of swap? Given your memory usage, assuming the above is "typical", and the fact you have 8GB RAM, I'm going to guess you could likely get by with no swap device at all. You have nothing to worry about. Unless of course this is an "idle" state, and you run some gargantuan simulation app that eats all 8GB when launched. I doubt that's the case, as you'd not be asking this question if you used such an app. From what you've provided, you don't need to worry about memory.
