Meta's CRAM technology provides better performance and efficiency than ZRAM and Zswap by offering hardware-offloaded compression with near-native DRAM speeds.

Meta Developing Compressed RAM "CRAM" For Linux: Better Than ZRAM & Zswap 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 CR… https://www.phoronix.com/news/Linux-CRAM-Compressed-RAM
