Speed problems when copying across network?

Gb small B if you will and I think you knew exactly what I was talking about. It works flawlessly and has been working flawlessly for me for over and year and a half now. Even the older builds had no problems with Gb lan. I've been moving larger .iso's and music accross my network with no problems not ever.

Blaming the Op system for this problem won't get you far. I'm not sure what you mean by falls apart but I certainly do not have that problem. If your having a problem it's absolutely not the Op system at fault.

Do you work for Microsoft? Looks like... It works fine for me too in many machines, but in some it does not, and in the very same machine where I get really bad speed with windows default copy, using Microsoft Robocopy or Fastcopy or Teracopy,I get full speed.

I work in a place where we have about 50 machines, several RAID fibre channel storage chassis, from different vendors like Facilis, AVID, and Autodesk, have several machines with 10GigE cards where I get speeds of about 900 MB/s... almost every vendor gives away its own copy utility because Windows copy can not achieve full speed.

The fact that is flawless on your system, it does not mean that is flawless on other people machines and that the OS is flawless.


So the fact that other utilities can get on the machines where I have 10 GigE about 900 MB/s and Windows can barely do 150 MB/s is not a Windows copy flaw???

The issue is with your own network, Windows 7 has no such problems I can assure you of that. I move files all the time and never have any problems getting 1GB speeds accross my network. Time for a hardware upgrade I'd say.

Wow, nice to be so arrogant towards people just wanting help.

It is not with my own network. None of the hardware is over a year old, it all worked under Windows XP Pro.

1GB is memory not speed either, had you said 1Gbps then maybe I might assume you know something about the subject area. You'd never get that speed on a gigabit network either, it's the theoretical maximum with no overheads.

Now that you mention the max of speed, I was surprised yesterday when after a few changes on my card setting and changing to a new switch, I got about 127 MB/s

The things I've changed was enable jumbo frames, and enable all of the "offloads" of the card on my notebook, and got a new switch that support jumbo frames, I cam tell you the model later if you want

I was under the impression that if you connected two computers directly without switch that I would get the maximum possible speed, but it seems I was wrong, using an IP capture tool, hundreds of packages where lost that way. What is curious that fastcopy didn't have that much of a problem connected this way while windows copy did.
