Well it definitely is more efficient but RAM is still RAM… Swapping whole 8 gigs will make your system sluggish no matter what. I feel like 8GB is fine if your usage is really light, but swapping more than 70% will slow it down extensively. On the other hand there is a whole camp of people who run heavy dev suites on 8GB and don’t have these issues, so it might really be a faulty line. It’s the first version in the end.
