What Is zRAM/Swap?
How to Enable zRAM / Swap in Any Custom Rom – MT65XX. zRAM is a Linux kernel function that gives a form of virtual memory compression. zRAM increases overall performance by way of keeping off paging to disk and the usage of a compressed block device in RAM instead, inside which paging takes area until it is essential to apply the swap area on a hard disk drive. since using zRAM is an alternative way to provide swapping on RAM, zRAM allows Linux to make a better use of RAM when swapping/paging is needed, specifically on older Devices with much less RAM installed.
