Chapter 7: Memory Management & ZRAM

Mobile hardware faces significant RAM constraints. To overcome this, we implement ZRAM—a kernel feature that creates a compressed block device within the RAM itself.

1. Compression Logic

By leveraging a 2:1 compression ratio, we effectively expand available memory for heavy compilation tasks without relying on slower physical storage swaps.

# Check ZRAM activation status
$ zramctl

# Analyze swap priorities and mount points
$ cat /proc/swaps
