What is zRAM

zRam is an experimental (staging) module of the Linux kernel. It was previously called “compcache”. zRam increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive. Since using RAM is faster than using disks, zRam allows Linux to make more use of RAM when swapping/paging is required, especially on older computers with less RAM installed. (From Wikipedia)

This is another method they are planning to use to make Chrome OS work better, by handling RAM efficiently. There are other linux distributions that can already be tweaked to get better performance. zRAM on Chrome OS

There are already geeks playing with zRAM on Chrome OS. It needs some commands and some testing to get this working. By making zRAM enabled by default on Chrome OS, they can get things working really easy, and also tweak them to their preference. But for normal users, this just means performance boost, which is always welcome.

To add Zram to your chromium for raspberry pi 2 os

simply place the script which can be downloaded here http://www.mediafire.com/view/91iybeeycy149n1/zram.conf

into the etc/init folder

and after that you will have Zram active by default
