weird network performance

Hi,

I just got in a new Relion 430 server from Penguin Computing. It has three network ports and I am using the 100 Mbit one.

Below is the output of ifconfig:

eth0 Link encap:Ethernet HWaddr 00:E0:81:25:7A:05
inet addr:128.206.22.161 Bcast:128.206.23.255 Mask:255.255.252.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:7239733 errors:120306 dropped:0 overruns:10 frame:120306

Interrupt:17 Base address:0xa400 Memory:fd7fe000-fd7fe038

The number of errors is what is puzzling me. The network performance seemed very flaky and slow so I suspected a bad cable. After
changing it, the performance has not changed much and the number of errors continued to grow. I am not really sure what kinds of errors
does the "errors" field refer to. Anyone can shed any light on this and give me an idea of what I am looking for?

Below is some information about the card. Kernel is 2.4.20.

Intel(R) PRO/100 Network Driver - version 2.2.21-k1
Copyright (c) 2003 Intel Corporation
e100: selftest OK.
divert: allocating divert_blk for eth0
e100: eth0: Intel(R) PRO/100 Network Connection
Hardware receive checksums enabled
e100: eth0 NIC Link is Up 100 Mbps Half duplex

Thanks,
Ognen

To answer my own question, the problems were solved by switching to
another network adapter in the same box, seems like the one above is
somehow faulty (the one above uses the e100 driver and the new one uses
the e1000). Seems like the errors field can get set when there are
hardware errors...
