I recently added a new server to my LAN that has a 1gig network card and I've encountered a problem with copying large files between the new server and my machine which also is supposed to have a 1gig network card.
However, when trying to copy a 2.34GB file from "my machine" to the new machine, the file takes about 2 minutes to copy.
The SAME file copied from the new server to my machine takes about 40 seconds.
There is obviously a bottleneck somewhere and my suspicion is that it is on "my machine" having problems sending the file. I have attached a LAN usage from task manager. I've played with my network card settings such as jumbo frame size, checksum offload, etc and the speed still drops as shown in the attached images and just spikes here and there. I've even tried matching the settings on the server with the same effect.
My machine -> server = SLOW (slowcopy.gif)
Server -> My machine = FAST (fastcopy.gif)
