    SubjectRe: How can I help with VIA MVP3 problems?
    I'm not on the list so please also reply directly to me. I may soon be done :-)

    I was made aware of the following:

    I hadn't noticed that before and it helped me improving the test. By ensuring
    that the two kernels looked at the same size RAM I found that the performance
    numbers were the same.

    However, I then now wonder why my system gets slower when increasing the amount of main RAM?

    Is it a RAM caching problem in the chipset or the board similar to the braindead
    Intel VX430 chipset that couldn't handle more than 64MB? I hope not, but I can't
    see any other reason, even though I thought such problems were of the past?
    Please let me know if you know something about it.

    I found the following relations with regard to memory settings. As the 2.2 and
    2.4 kernels I use performed the same with little RAM (64MB), I stayed with the
    2.4.4-ac8 for simplicity's sake.

    A 2.4.4-ac8 kernel build:

    2.4.4-ac8 with 64MB RAM mem-setting: real 8m26.180s
    user 7m5.340s
    sys 0m39.430s

    2.4.4-ac8 with 128MB RAM mem-setting: real 8m20.902s
    user 7m8.810s
    sys 0m39.800s

    2.4.4-ac8 with 160MB RAM mem-setting: real 8m21.653s
    user 7m13.830s
    sys 0m37.840s

    2.4.4-ac8 with 192MB RAM mem-setting: real 9m48.632s
    user 8m39.270s
    sys 0m39.740s

    So it seems around here the performance starts to decrease.

    I am still puzzled why the shared memory like the following is always zero on
    the 2.4 kernels? All I can remember checking it on has it like that, but I can't
    find any explanations about it?

    Swap: 542859264 147456 542711808
