Windows DFS File Transfer Speeds

Running Windows Server 2008 R2:

We are looking to impliment DFS into our enviroment.  After working with Microsoft for nearly a month, I finally got inital replication fixed and completed.

However, after doing some testing, I was not thrilled by the file transfer speeds.

For example:
I'm on the same LAN as our file server.
When I copied a 150MB file from the file server to my desktop, I saw speeds around 10MB per second

When I switched over to using the DFS share, I copied the same file to my desktop, but the speeds were now around 1MB per second.

Is this a limitation of DFS or do I perhaps have something still setup incorrectely that I failed to cover with Microsoft?

Are you pulling from the local server, or a remote target? To find out, go to properties on a folder and go to the DFS tab. It will show you the possible DFS referral targets, and which one is being used. My guess is that you are pulling from a server over a WAN connection.

I verified the DFS referral target is the local file server on the LAN

Thanks!  It ended up being an issue on the referrals.
