    If we decrease the size of Linux Swap memory, what are the problems we may have to face. My RAM is 512 MB and my swap memory is 350 MB ,I face a problem regarding speed and smoothness of the processes. If u know any thing please reply.

    Dude, don't post your phone number.
    Also, you might get a quicker/better response if you posted in the linux sub forum.
    The current swap size should suffice plenty for running multiple apps though.
    Is it too small? Is all that 350MB actually used?

    swap kindof works as your RAM, or virtual memory.

    but you will get a better response on a proper linux forum, try http://ubuntuforums.org

    Why do you want to decrease the size of your SWAP partition?
    Is it possible? yes. It is recommendable, no, especially if you're running a heavy DE like Gnome.

    The only problem you are going to face is potential slow down due to lack of memory to hande multiple processes.

    Hibernation won't work as the swap partition is usually used to store the system state (aka what's in your RAM).

    512MB RAM means the system definitely will use your swap as virtual RAM. Reducing it will likely reduce the overall performance.

    I would keep the same swap space or even increase it. 512 MB is not a lot of RAM, and it's likely you will need swap space in normal use. Though this is probably not what is causing your performance problems; if you don't have enough swap space, your computer will crash, not just slow down.

    Also, as QualitySeeker points out, for hibernate to work your swap partition has to be at least as large as your RAM, because hibernating writes the contents of RAM out to disk.
