Windows 7: Copying files over Win 7 network keeps stalling?

Hi folks,

I already posted about slow network copying speeds but have discovered that's not the issue.

The actual issue is that copying keeps stalling. It'll copy files for 5-10 seconds at a good speed and then it just stops for maybe 30s - 1m? It repeatedly does this which makes it look like the network is slow.

Any thoughts on settings in my cards (Intel and Atheros gigabits cards, Netgear gigabit switch) I can change or something in Windows?

Cheers!

I'm seeing the same, and it does not happening if I use fastcopy, have you tried? Still want the regular copy to work, but seems to be just bad.....

I was going to try TeraCopy again but that should be like fastcopy

Are you by any chance trying to drag and drop those files using Homegroups?

No I am not.

Things changed for me after changing to a new switch that supports Jumbo frames and enable the card to use it, also after enable all the "offloads" of the cards, the system was less affected by these slowdowns, using windows Copy, because using fastcopy always was faster, but now is even faster.

You can use an IP capture tool to see if you start dropping packages when windows is stalling, Wireshark is very good

I think I mentioned in the other post that hardware upgrades were a possible fix so I'm not too surprized that using a new switch improved the copy problem.

yes, improves it using windows copy..... using fastcopy is the same. Fastcopy always gave me the full speed, even before the change of hardware. Still think windows copy is flawless when other copy utilities can do it faster, even over a not so good switch?

The amount of dropped IP packets using windows copy is a lot higher than fastcopy.

Thanks for giving me credit for causing you to change over your hardware, now try using a router with GB LAN and WAN like I'm using and don't forget to update the firmware.

If you are dropping packets then you have an underlying problem of some sort, I never get any dropped packets and have never had a stalled copy problem so I'm not sure what is causing that but there must be an underlying problem.

you are missing the picture here... we are talking about a problem of windows copy having problems with certain hardware when other apps do not have the problem, and you in a very arrogant way jumped to us saying that windows is flawless when we are trying to find what the problem is.

the dropped packets where in direct connection between two machines, and with windows copy, not with fastcopy, no switch in the middle. And actually what I did was to activate the jumbo frames, the switch already had the option but I did not know about it. And Fastcopy was giving me full speed even with that option turned off.
