how fast is 100Lan really suppose to be?

I am currently able to copy a 415MB file in just under 7 minutes. That comes out to be almost exactly 1MB/s from anyone of my computers to another. Now I assume that 100mbits/8=12.5MB/s throughput, and I know TCP/IP has some overhead as well as cable lenght and hops through router, however I think 1MB/s is a little low.
Can some other people give it a whirl and post results to give me an idea?

From SCSI machine to SCSI machine (IE no CPU overhead involved), about 11 minutes for 4gig over a 100meg network using a Cisco switch.(Uncompressed data). Your data speeds are what I would expect out of a 10meg system.

Are you using a crossover cable or a hub / switch?
If using the hub / switch check to see if you are getting sh*tloads of collisions, check to make sure that your cables are fully twisted to the RJ45's (any length over about 50mm straight will start to affect performance).

If your network cards are dual mode, see if they have an indicator light, and that the light is indicating 100 connection.

I found it to be a faulty cable. I did the cables in my house myself and screwed one of them up. The one going from router to hub. Now I am getting around 7MB/s, so same file copies over network at just under 1 minute :)

Good on yer!
Actually I did my own as well at home, I just use a simple hub, I only run a 10meg network, as I have a couple of K6 2 450's with 10meg cards in them still in use, so my atrocious cabling does not really come into play!

hi i have a PCI 4x ethernet hub, one of the port has a up/down switch. and seem to work with my asdl modem but the other ports dont work.

can u explain the workings of these cards to me, the manual wasnt very helpful

@lilhobo

That switch is will enable you to daisy-chain routers into the port with the uplink switch without having to use a crossover cable.

Plug the second router into the port on your primary router, flip the switch, and presto, more ports available!
