| |
Hi,
I have one requirement: I wanted to have a swapfile (64MB to 256MB) on my system. But I wanted the data to be compressed and stored on the disk in my swapfile. [Similar to zram, but compressed data should be moved to disk, instead of RAM].
Note: I wanted to optimize RAM space, so performance is not important right now for our requirement.
So, what are the options available, to perform this in 4.x kernel version. My Kernel: 4.9.x Board: any - (arm64 mostly).
As I know, following are the choices: 1) ZRAM: But it compresses and store data in RAM itself 2) frontswap + zswap : Didn't explore much on this, not sure if this is helpful for our case. 3) Manually creating swapfile: but how to compress it ? 4) Any other options ?
Thanks, Pintu
