This is a part praise/part slam post,
First the praise:
I pulled Red Hat 5.0 out of the box, and on the first try it installed
with a 3COM 3C905TX PCI card. During the install I put in the DNS, my IP
address, etc... There is no router for the issolated 100 megabit
I am in so left that blank. It came up like a champ and I could lookup
and ping/ftp/telnet with no problems whatsoever.
Now the slam:
I am very, very disappointed with the performance of this driver. Its
card, and I suspect I have something misconfigured in the RedHat setup.
just short of a amazingly slow. On an issolated 100 megabit Ethernet LAN
30 or so machines I get these kind of performance numbers FTPing
from a monster AIX server:
OS/2 4.0: 1760K per second
Win95/NT 4.0: 900-1000K per second
my RedHat Linux 5.0: 19K per second
Yes, you read that right. 1760K per second on OS/2, 19K per second on
Now mind you on OS/2 it pretty much locks the box solid and squeezes the
out of the Pentium Pro 200, while it is transfering at 1760K, and
get lower numbers like 1500K or less depending on what other people are
On Linux all network traffic I can muster corresponds to less than 2% of
and the machine is virtually idle. I am multibooting between OS/2 and
Linux on the same box with the same card, on the same port, so there
be NO hardware differences. I even checked the hub and the card to make
it was connected to the ethernet at 100 megabit on both OSes.
So I would really like to use Linux as a backup server for the AIX box,
can't justify using something that performs at less than 1/10th (almost
the other operating systems. What am I doing wrong? Is there something I
tweak to up the performance of network I/O? As is its not using hardly
any of the
bandwidth that is available.
Any and all help is appreciated,
