If you are on Firefox and you run into an overall system slowdown, check how many subprocesses it has spawn. With the release of Fission (their website isolation tech) this number becomes unbound. In my case it was close to 100, each eating up at least 50MB with some well into hundreds megs. It was a swap fest. Not sure what they were thinking, but a simple post-update warning would'be been nice... or perhaps it was there, behind all that "aww, let's select your mood color" nonsense that now refularly surfaces after every second update. In any case Fission is easy to disable once you know it exists.
