Interesting blog post about zswap functionality

Posted 06-25-2014 at 03:31 PM by the dsc (linux-related notes)
Tags ram, swap, zswap

Zswap is basically like a "fake swap partition" inside the RAM itself, but instead of just "moving" things from one place to another in the RAM, these things are compacted, instead of being written to the actual swap partition, on the HDD. Or so I understand. It then squeezes more out of the RAM than with non-compressed use, at some cost of CPU due to the compression/uncompressions, and monitoring, but sparing access to the swap partition on the HDD.
