Meta Developing Compressed RAM 'CRAM' For Linux: Better Than ZRAM and Zswap?

Phoronix reports on a presentation this week by Meta engineer Gregory Price at the Linux Plumbers Conference in Prague: With today’s memory shortages, high prices, and ever increasing memory capacity needs, Meta engineers have been working on Compressed RAM (“CRAM”) for Linux. This hardware-offloaded compression still allows cacheline/byte access to compressed memory and in turn a better implementation than the likes of ZRAM and Zswap. Very promising is that there is near-native performance to raw DRAM speeds with CRAM…
