Creates virtual block devices called /dev/zramX (X = 0, 1, ...).
|
|
Pages written to these disks are compressed and stored in memory
|
|
itself. These disks allow very fast I/O and compression provides
|
|
good amounts of memory savings.
|
|
|
|
It has several use cases, for example: /tmp storage, use as swap
|
|
disks and maybe many more.

See zram.txt for more information.

Enable statistics collection for compressed RAM devices. Statistics
|
|
are exported through ioctl interface, so you have to use zramconfig
|
|
program to get them. This adds only a minimal overhead.
|
|
|
|
If unsure, say Y.
