    Subject2.4.x high irq contention
    Hi people,

    This is 2.4.21-pre4aa3, but the same applies to 2.4.20-vanilla, and i
    think to any 2.4.x. The NIC is RTL-8139(8139too). I would really like to
    know what could be done in this situation. The machine (p3-1GHz) is almost
    unrespobsible. Yes, there are really network card interrupts. So, here it goes.
