Episode 14 of The Linux Podcast with Fexingo dives into the quiet revolution in Linux memory management: Zram. Lucas explains how Zram creates a compressed block device in RAM, swapping pages before they hit disk, and why it dramatically outperforms traditional swap on SSDs for most desktop and server workloads. Luna brings up real-world benchmarks from Phoronix showing up to 40% better responsiveness under memory pressure, and the episode discusses the kernel resources Zram consumes, when to use Zswap instead, and Fedora's decision to enable it by default since version 33. A concrete, technical conversation about compression algorithms (LZ4 vs ZSTD), memory savings, and what this means for the average Linux user. No fluff, just practical systems knowledge.
