Copying files over Win 7 network keeps stalling?

Hi folks,

Any thoughts as to why copying files over a network would keep stalling?

All machines are Win 7 64. All have latest network drivers (Intel gigabit, Atheros gigabit and whatever my laptop has). Also have a Netgear gigabit switch sitting in the middle of it.

The overall speed is fine for 5-10 seconds then it'll stall for 30 seconds to over a minute or two at a time which obviously means copying can take an age and is rather annoying.

Any thoughts on what settings in the cards or Windows would cause this?

Cheers :)
Paul.
 
Had this problem with a few win7 machines

I think it is a new "feature" in this version of windows

Example:
1. I try and copy a file across the network from a fiber attached SAN to my PC , it moves at about 1Mb/s or slower :(

2. I pull out my lan cable hold it out for 5 seconds and put it back in , copy the
same file and it now goes at about 70MB/s

My PC is dual boot , so if I load up Xp 32 on same hardware with same network connection it runs at full speed every time , windows .. getting better every version ..... my ****
 
Yeah it is very odd. I've had transfers not jam and fly and then try again a bit later and it just stalls.

The reason it looks slow is the stalling adds up to the time taken even if the bursts are 70MB/s when it's actually copying.

Going to see if Teracopy makes any difference to the way files are being copied this evening.
 
have you tried updating the network card drivers from the mfg web site?

maybe also try forcing 1000meg full duplex (reboot pc and rooter) then knock it down to half, then try 100 full and then half..

you need to reboot the router / hub / switch each time really incase its a crappy one will not realise anythign has changed..
 
Drivers are all up to date.

Yep, I've tried the forcing thing. As I say it's not a speed problem, the copy actually keeps stalling.
