Episode 60 of The Linux Podcast. Lucas and Luna explore how ZRAM, a Linux kernel module that creates a compressed block device in RAM, is changing memory management on everything from Android phones to enterprise servers. They break down the trade-offs between ZRAM and traditional swap, explain why it delivers up to 50 percent more effective memory under load, and discuss how modern kernels handle compression algorithms like LZ4 and ZSTD. With real-world examples—like Google's Pixel phones using ZRAM by default and servers at Dropbox tuning swap on ZRAM for better density—this episode gives you a concrete understanding of a silent efficiency hack in the Linux kernel. No fluff, just the mechanics.
