Network throughput

Gryfndor · Posted: Wed Sep 01, 2004 12:14 pm Post subject: Network throughput

I downloaded the 2 gig file for WOW onto my laptop at a buddies house the other day, and when I got home I pushed it to my computer on my 100 meg network. I was semi pissed when I found I was only achieving 60 - 70% of my bandwidth. Both systems were 3 gig plus P4's well equipped. All I can figure is that my hub must be junk. Any of you looked in to this before ? Shouldn't I be seeing a 100% bandwidth usage ?

so, how long did it take to transfer the 2 gig file?

what are you useing for hardware? are you useing firewire?usb2.0? or just cat6 or 7 network with say a netgear hub?

This is because CAT7 cabling is in it's infancy. It is very expensive and there's almost no practical use for it yet. Razz

The last thing I read about cat7 was it is a European standard and it is a shielded pair cable similar to a T1 cable wear each pair has its own shield and drain tap with a over all shield to boot
As a installation tech it sounds like a night mare but the again so was fiber when it 1st came out

how do you like the new fancy name installation tech = cable jockey Rolling Eyes

LMAO

Took me 5 min to move the file accross the Network. I had my system with a 1 gig network capable card and my work laptop also 1 gig capable. They are both 3 gig plus P4's with lots of ram. I'm using a simple cheap ass hub not even sure the brand on it netgear is a real possibility. I had a decent router but its wireless capabilities became somewhat useless when I lost my broadband connection. I'm going to try connecting the two systems directly this weekend and look at the throughput. I don't have any networking using Firewire or USB.

My guess is that your NIC drivers have the default setting of 'Auto-detect' in the Link Speed and Duplex configuration. If you think your max speed should be closer to 100/full, try changing it to that on both NICs, and see if that raises the speed. Chances are good, though, that your hardware is the chokepoint, keeping the speed down a bit.

From what I'm getting out of your posts so far, Gryf, you're using a 100mb hub? If so, 5 minutes is a good time. You're getting 100% of your possible bandwidth utilization.

I can get pretty much any cable for pennys on the dollar, we use gigbit LAN with CAT6 and our file transfer between mine and Jerz PC is about double what my older NIC's and onboard ports transfered. few nights ago i installed wow from my shared drive to hers and was almost the same install time for a 2.2 gig file as it was just to stright install on my PC.

Does gigbit make NIC cards? I havent ever looked but I'm sure they do?

There are Gigabit network cards out there. We have them in our Alpha systems (3 per). Now if only the network would have upgraded when they were scheduled to upgrade.

Yea, you can get complete sets of gigabit hardware.

Gigabit can be achieved with CAT5e, but CAT6 is optimal.

CAT7 is supposedly intended to be an alternative to fiber, which is hugely big pipes over long distances (hence the shielding).

Changing your hub for a switch can sometimes make a drastic improvement in performance. Switches reduce network collisions to nearly zero. If you've tried all else with no improvement, analyze your network.

It's also possible, depending on your form of broadband (DSL vs Cable, etc.) that you are competing with people in your neighborhood for bandwidth.

I've seen cablemodems go from 3Mbps to 2Mbps throughput because someone's neighbor got the same service, making less working bandwidth available.
