    Subject2.4.2ac7 success story, one question

    since of course all anyone hears are the disaster reports, i just
    wanted to throw out my experience so far with 2.4... 2.4.0 and 2.4.1
    didn't work very well on my box (a Dell Latitude CS-X laptop, PII-400,
    256MB RAM, 20GB IDE), but i'm currently running 2.4.2-ac7 with no
    problems at all. the only difficulties i've had are that i've tried
    the in-kernel PCMCIA on each 2.4 release with no luck (nothing works
    with all my Ethernet cards, primarily my Farallon cardbus tulip card,
    but also with my wavelan wireless and IDE cards), so i use David
    Hinds' drivers.

    performance in general screams, but sometimes when i start up a large
    process (netscrape, or vmware) it dogs down for a couple seconds.

    the one question i have is about VM. the machine has 256MB of RAM in
    it, and i never get near this usage with the actual processes
    running. nevertheless, /proc/meminfo says:
    danube:/# cat /proc/meminfo
    total: used: free: shared: buffers: cached:
    Mem: 262098944 257241088 4857856 0 81330176 91557888

    if 90MB are just cache, why do i have ~55MB swapped? i'm not sure how
    to see exactly how much of that swap is really being used or how often
    things move in and out of swap, though.
