    I have 311MB of swap used, but why? I am only using 6.35GB out of my 16GB of RAM. Shouldn't there be no swap used?

    The only explanation I've seen that makes sense to me is:

    Windows does it too. I have a server that has 196GB of RAM, and the most I've ever seen used is like 50GB. It too swaps out a small amount even though it's nowhere near using all of the available RAM.
