On a related perspective zswap (Linux) is surprisingly efficient if the system isn't CPU-bound.
It is "a Linux kernel feature that provides a compressed write-back cache for swapped pages, as a form of virtual memory compression. Instead of moving memory pages to a swap device when they are to be swapped out, zswap performs their compression and then stores them into a memory pool dynamically allocated in the system RAM"
