RE: Slow Network Connection
I changed the driver from e100 to eepro100 with no change in network speed.
Even when I use the on-board NIC (Marvell) I get slow speeds so I don't think it's related to the driver of the NIC.
Could the IRQ that my NIC is assigned make a difference? I also noticed for the 'cat /proc/interrupts' that PCLinuxOS is using IO-APIC-level vs Debian's IO-APIC-fasteoi. Could that be my problem and how can I change it?

Subject: Slow Network Connection
I just purchased a Shuttle XPC SN27P2 barebones system.
Chipset: North Bridge - Nvidia nForce 570 Ultra
Onboard NIC: Marvell 88E1116(10/100/1000Mbps) - I also added a Intel Dual-Server NIC and disabled the Marvell
I tried installing Debian 4.0r0, 4.0r1 and a nightly test build and they all suffer from the same problem; an extremely slow connection to the internet (about dial-up speed - I have a 5Meg cable connection).
Yet, if I boot off of a PCLinuxOS Live CD the network works perfectly.
I've changed cables and network cards with no luck. I'm hoping someone here will see something that I've overlooked.
Thank you.
