Re: 2.4.0-test3 Why is my system swapping rather than freeing the cache ?

    Kernel 2.4.0-test4-pre6

            total: used: free: shared: buffers: cached:
    Mem: 30855168 30105600 749568 0 401408 12279808
    Swap: 21151744 18051072 3100672
    MemTotal: 30132 kB
    MemFree: 732 kB
    MemShared: 0 kB
    Buffers: 392 kB
    Cached: 11992 kB
    HighTotal: 0 kB
    HighFree: 0 kB
    LowTotal: 30132 kB
    LowFree: 732 kB
    SwapTotal: 20656 kB
    SwapFree: 3028 kB

    Quite a bit better didn't see SwapFree hit 0 this time though I wonder
    what my performance would be like if cached < swapfree.
