NAME

       zramswap - configure swap on zram

SYNOPSIS

       zramswap [OPTION]

DESCRIPTION

       zram is a Linux feature that allows a user to create compressed ramdisks.

       zramswap sets up swap in zram, which effectively allows you to compress memory.

       Common use cases:

       On  machines  with low memory, mitigates the tedious situation where the machine is out of
       memory and then it starts swapping to disk only to lose a large amount of disk bandwidth.

       On machines where the main swap file  is  on  flash  memory,  zramswap  may  only  provide
       marginal  performance  increase  (especially  on fast SSD media), however, it will prevent
       some amount of wear on your flash memory. zramswap is especially beneficial if  your  main
       flash is on SD/MMC/CF card.

       On  servers  that run many virtual machines or containers, zramswap allows you to optimise
       memory usage by swapping out data that's not often accessed, but  when  a  user  needs  to
       access  it,  it  will  be  available  fast.  It  allows you to overcommit on memory with a
       negligible hit on your application performance (and often an  improvement  in  performance
       where you can use more main memory for filesystem cache).
