The new method allows access using standard memory semantics instead of as a block device, drastically improving performance.

    CRAM is an utterly goated name

    So there are some benefits to the ram crisis? People actually optimize things because of limited resources.

      You know it’s getting weird out there when Meta seems to be doing something that’s actually useful.

        They’ve been doing useful engineering things since the start, it’s just that it pales in comparison to all the bad things

          They only did a few useful things to be more efficient in doing the bad things

      Does it count as optimization? For supported hardware, it’s certainly cool. But it’s not making inefficient software better, it’s making better use of the hardware.

        Ya, but those worked. Wasn’t it originally called Disk Doubler (think it might have changed names when MS purchased it).

        I remember finding a bug in it that took forever to figure out. You had to install windows 3.1 before enabling it or it would fail to read one of the floppies.

        Took me a LONG time to figure that one out…

    I can carry nearly 80 gigs of data in my head. One sixty if l use a doubler.

    But you need a CXL device which does the (de)compression in hardware between the CPU and RAM?

    What are the real world effects of this? E.g. for gaming etc.

      None, your current hardware lacks support for this.

          In the presentation, they talk about a compression chip: https://www.youtube.com/live/OPRciCSsdS4?t=2060

      If you’re running out of RAM you can use the faster CRAM instead of ZRAM which itself is already much faster than swap. Basically you can fit more data into your RAM

    So, from what i’ve got from the comments; instead of doing swap shenanigans except in RAM like ZRAM (which slows it down), it just compresses content to a separate portion of RAM and points there?

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
