Isn't swap just an extension of system memory? Isn't adding 4GB of memory just as effective at preventing out-of-memory as dedicating 4GB of HD space to swap? I can understand enabling swap on a laptop or other system with constrained memory capacity, but doesn't it make sense to disable swap and add memory on a 24GB server? Is swap basically a way to save money on RAM? - Grant
