We've run into a weird issue today when copying files from a Windows Server 2008 R2 (SP1) to a Windows 7 Prof. client. If I initiate the transfer from the Server 2008 box I'll get 80-100MB/sec which seems to be what I'm expecting. As soon as I initiate the transfer from the Windows 7 client end then I'm getting speeds closer to 40-45MB/sec. We've created a Ramdisk to avoid seeing limitations from the local storage for the tests. This was consistent over multiple runs.
The test file is about 3GB in size.
I also don't think that it should be related to caching. I created the files with different sizes for every run to be sure that I'm not seeing any caching effects.
Any explanation for that?
Thank you, Felix
