    I recognize my own material, but I can't grasp how it applies to the
    several questions you ask. My quote speaks to simulating a small ram
    situation. My rig has 4 Gb and it is my understanding that without
    some cheatcode or other, I'd never see zram's effect. Hence the
    simulation.

    IIRC, above 2 Gb real ram, zram is never employed.
    There is a cheatcode which may be used to keep zram from being used
    for any value of real ram. That about exhausts what I know about zram.

    For some of the more experienced forum members, I think you should
    spell out in some detail what you are trying to do and what the
    particulars of your Knoppix install is. Maybe they can help you.

    Keep in mind that some of us use LiveUSBs,
    some have an hd install, poor-man's or 0wn, some use a virtual setup.

    In considering this topic anew I have the following thoughts.

    1. The general topic of swapping seems to apply here, it is only
    that a new device has been added to the list.
    There's lots of material on swapping; see apropos swap for example.

    1.5 Whatever your situation is, it would seem you might emulate
    whatever your swap questions are first using hard drive partitions
    to iron out the kinks. Once that is working, switch only the device
    designations for hard drive to zram.

    2. Knoppix has only one device, zram0. defined to use ram as a swap device.
    It may be necessary to re-compile the kernel fo provide additional such devices.
    I now recall another developer likes to split the 'zram' load among cpus
    if there are more than one available. Klaus K prefers not to do so.

    3. Klaus K has an interest in netbook applications of Knoppix, so
    his focus, sometimes, is in 'really small' values of ram (less, or much
    less, than a gigabyte). My situation is one of never needing swap, of
    any kind, since my apps never outrun my available ram.

    Let us know how things go for you.
