Description : creates RAM based block devices to act as swap disks
This project creates RAM based block device (named ramzswap) which acts
as swap disk. Pages swapped to this disk are compressed and stored in
memory itself.
Compressing pages and keeping them in RAM virtually increases its
capacity. This allows more applications to fit in given amount of
memory. This is especially useful for:
* Embedded Devices: Memory is scarce and adding more memory
increases device cost. Also, flash storage suffers from wear-leveling
issues, so its useful if we can avoid using them as swap device.
* Small Desktops (aka Virtual Machines!): De/Compression is much
faster than swapping to disks (include seek times!). Of course, you also
get to run VMs with much less RAM assigned. Total memory savings from
individual VMs can be quite significant if multiple VMs are hosted.
* LiveCDs : These typically do not have any disk swap configured.

Daniel
