Memory compression is an overblown feature. It's definitely cool, but it's a band-aid. We've had it on Linux for 3+ years now and the place where its found the most use is Android; that is, embedded systems that are difficult to upgrade trying to squeeze just enough RAM for one or two more applications.
In real life, memory compression is demanding on the CPU and they have to use a lightweight compression algorithm to keep response times snappy. It'll help sometimes, but in general, it's not going to make a machine with 4GB behave like a machine with 8. It might make it behave more like a somewhat-slower machine with 5.
