    Default Please clarify the memory usage

    Could anyone tell me if my memory status looks right (just looked at it accidentally in the InfoCenter):

    Used Physical Memory 78%
    Total Free Memory 21%

    Application Data 13%
    Disk Cache 85%
    Free Physical Memory 0% <- !!!

    Free Swap 100%

    I have 8 GB of RAM. Is 0% Free Physical Memory normal? What's the Disk Cache and why has it consumed all my memory?

    I notice my Linux slows to a crawl if I leave my computer running for a day or so then it takes a few seconds to do anything until I log out - log in. And that is with my spec! Is anything wrong with the memory? Is there a memory leak or something?

    Thank you.

    Yes, it's a good thing. Search for previous threads entitled "Linux uses all my memory" or "why is Linux using all memory" or something like that. I'm sure every newbie asks this question once in their journey.

    Yeah, after 7 years of using Linux I just had to ask this one. Doh!

    But it looks scary if you never knew. So, for all the "dumb" ones like me: Help! Linux ate my RAM!

    linux uses memory in a way better than windows, and what you see is
    normal, see more:
