I'm not familiar with Smart Sync, so can't comment on that. But can you reproduce the problem outside of that software? For example do you see the same slowness if you use RoboCopy or DFSR?
Take a look at this post: http://social.technet.microsoft.com/Forums/en-US/winserverfiles/thread/e55022a4-db65-4dc9-a2f1-96b7f5d8e2fa Even though you aren't using DFSR, it might give you some ideas. Specifically I'd look at the TCP off-load value . That might help.

I have two existing servers, X and Y. X will be replaced by a new server, Z. Then Y will be replaced by X, and Y decommissioned. These are rather simple file servers. When we brought Z online, we copied data from X to Z via Smart Sync and got fantastic transfer speeds. When we went to copy from Y to X, however, speeds are horrible. What should take several hours is taking days. We then tested communications between Y and Z and speeds are great again. All servers are on the same switch and reside in the same rack. Why would 2 servers communicate so slowly? X to Z = fast Y to X = slow Y to Z = Fast Results are the same whether we "push" or "pull" data.
