zram (also called zRAM and, initially, compcache) is a Linux kernel feature that provides a form of virtual memory compression. zram increases performance by avoiding paging to disk and using a compressed block device in RAM instead, inside which paging takes place until it is necessary to use the swap space on a hard disk drive. Since using RAM is an alternative way to provide swapping on RAM, zram allows Linux to make more use of RAM when swapping/paging is required, especially on older computers with less RAM installed
- An init script is installed that will start zram
- A companion script is copied in /opt/zram/zram_stats.sh that shows statistics about ram/swap usage.
Install a zram enabled kernel:
- uek kernels from Oracle Linux
- any kernel from an el7 distribution
The module requires a kernel with zram module.
It was only tested with OracleLinux 6 and OracleLinux 7 distributions.
