    Default High Memory usage by system

    Hi,

    I am running KDE4.3 on openSUSE11.1 x86_64.
    It is consuming 1758 MB of 1914MB (2GB RAM).
    How can I figure out and fix the problem??
    Regards

    Unless you got some software that has a memory leak then you should be fine, the rest should be just cache

    - rtfm; unzip; strip; touch; finger; mount; fsck; more; yes; umount; zip; sleep;

    using free command:

    The free output seems normal.
    See mine:
    total:4100488
    used:3969352
    free:131136
    shared:0
    buffers:68720
    cached:3050716

    Mem:
    -/+ buffers/cache: 849916 3250572
    Swap: 2618584 372 2618212

    Most(if not all) modern operating systems try to utilize as much memory it is possible because it is better than sitting idle. Also it is not that easy to identify the true free memory on linux. The free command for example will not show you what you are looking for. Search google about identifying the true free/utilized memory on linux.

    The "top" command is a lot better when you feel your system crawling and you need to find the program that is causing it.

    In other words if your system seems responsive you shouldn't really care about the free memory
