Swap doesn't make difference, just a parachute for your apps: give some work guaranties, but make things slower & eats resources of SSDs. I'm prefer add RAM as

  Without swap, your server could potentially become suddenly unresponsive, as memory pressure forces all your running code out. The system will still be thrashing, and even worse than it you did have swap. If you do have swap, then you get a slightly more graceful degradation, and hopefully a chance to fix the problem first. What you really want is to never have a severe out of memory situation, and you can do that either by getting enough RAM that you never use it all, or by killing stuff nice and early when memory starts getting low.
