Slow upload to Server 2008 DC, Downloads work as expected
- by Anthony
I have a Windows Server 2008 Domain Controller that I run as a do-it-all server. It has a GbE connection to the network and to every machine on the network.
Downloads from the server file shares work as expected, between 70MB/s and 80MB/s to all the machines. However, when I try to copy files back up to the server, speeds fall to 7MB/s-10MB/s. I've disabled flow control and large send offload properties on all the NICs.
I had this problem before and managed to fix it through some properties changes, but like an idiot, I never documented my fix and have since moved to a new server.
Any ideas what I need to do to get the speeds to be more symmetric?
EDIT: Remote differential compression is also disabled.
