Unstable Network speed

Hi,

 

Need a bit of an advise here. I'm having a pretty strange problem. I've installed a windows 7 virtual machine on my Unraid V6 installation. all the virtual drivers have been installed according to the Wiki, but i'm seeing really slow speeds when downloading from the internet using my FTP.

 

I have sort of sorted the problem, but it would be nice i someone could explain to me why i'm seeing this behavior.

 

When i was looking at the nic i windows it was connected with a speed of 10G. When looking at perfmon in windows the network utilisation looked like a saw and after about 1 min of downloading, the speed was down from apx. 250Mbps to max. 100Kbps.

 

After some pulling in my hair i tried to change the network adaptor speed to 1G, and that solved the problem. Now i'm seeing completely staple speeds at 280Mbps, when downloading using FTP from the internet to my unraid raid.

 

It seems that my network droprate on the nic's is fixed too

 

Any good explanations would be apreciated

 

br,

Thomas
