Data Transfer via Lan

[NooBieless]

Hello everyone

Im having a bit of a problem with my home connection.
**This is abit hardware and Software

Got a hub set up which is 1gb, and 5 PC's with 1gb Lan cards... but when i transfer Data from 1 PC to another... it still only copys at 1mb - 5mb/s, this is really bugging me.

If anyone knows of any Software thats better for data transfer via lan, could u tell me.

Sorry if this was in the wrong section.
Thanks guys

You need Cat6 (iirc?) ethernet cables .......

Not sure what the problem is, you might want to check your lan cables, otherwise try this: http://www.codesector.com/teracopy.php

Teracopy as pointed out above is a good idea.

Check that the cards in the PC's are actually connected at 1.0Gbps and are running at full duplex. (check under network settings)

Please post the make and model of the hub you are using. If you have any NON 1.0Gbps devices plugged into the hub (printers, media players etc) unplug them and repeat your copying speed tests.

You likely have a bottleneck somewhere else. The network card can only transfer data as fast as your harddrive can supply it to the cpu and to the ram etc.

Remember 1Gbps can only transfer at 125MBps in a perfect world. Your harddrive won't be able to reach that speed, if the data on your harddrive is fragmented you will lose more transfer speed. If you antivirus is scanning every file and is slow this will also slow down the transfer.

1-5MBps sounds incredibly slow though.

Getting 1 Gbps LAN transfers is an exercise in futility and rarely works properly IME.

Well, if you are using a "hub" it explains everything. If it is actually a "switch", you may have the problems as outlined by the other posters.

Are you definitely getting 1GB connections though? Is this the actual connection speed when viewing it on the relevant pc's?
Why I ask, is because I had a similar problem, and turned out that it was just the cables that were wrong...
does not have to be cat6 but at least cat 5e.
And certainly, a hub is not the way to go... broadcast will congest...

I dont think i have a ethernet cable problem... i thought it was software but it turns out it might be the lan Card it self , the Server's Lan Card

 

[bubbatentoe]

It's probably a cheap switch.
They all say one thing but do something else altogether.

Make yourself a cross-over cable and connect PC 1 directly to PC2.
Copy the same files and test the speed.

It'll at least give you an indication of the PC's maximum transfer rate.
Your PC's probably can't write data faster than 40-odd MBps anyway.


see tomshardware tests.

Yup, I carry around a crossover cable in my laptop bag, u never know when you might need one...especially if you find another gamer in the airport smoking lounge...lol

 

[NooBieless]

yeah it looks crossover cables are the answer

Had the same issue some time ago, although it was on the 100mb lan. Trying to remember what I did...

It was one mashine that just couldn't get the transfer rate. As luck would have it, also my file server.
Remember it was something todo with the network card, TCP in the registry on the server. Basicly having to reset the network setting and card drivers.
Somewhere in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet

I remember that I deleted the key in the registry and the network died. Even after a reboot the network was still dead. After deleting the network card from device manager and rebooting again. Then allowing windows to reinstall the network card did the network came back and the problem was resolved. Still are.

Sorry, was very long ago that I had to do this. Remembered the website did say that it could brake the network on the OS and could result in having to reload the OS.

Many simultaneous copies *could* also be a bottleneck. try using SuperCopier to combine all your copy streams.
