Today’s article explores zRAM, a lightweight and efficient Linux kernel feature designed to improve system performance by using compressed RAM as swap space.
What is zRAM?
zRAM is a Linux kernel module that creates a compressed block device in RAM and uses it as swap space. Instead of writing swapped memory pages to a slower disk, zRAM stores them in compressed form directly in memory.
This helps systems with limited RAM perform better by reducing disk I/O, improving responsiveness, and … Read More
