    Well, that used to be the rule of thumb for a Linux-specific problem
    with swap space. Today, you can run without swap without a problem.
    I keep a gig of swap on hand to avoid out of memory problems at all
    costs and have never hit that.

    A sane default today would be to set your swap size to at least the
    size of your current physical memory. I suggest using a swap space
    equivilent to the maximum amount of memory your board can support,
    though this is generally considered massive overkill given how cheap
    RAM is these days.
