Subject: 2.4.x high irq contention

Message-ID: <20030422033201.GA523@casus.home.my> (raw)
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.
