The problem is the initial copy, which takes forever if you have a small link and lots of files. We're running into this issue with Snapvault.
Also, if you have a LFN (Large Fat Network) where you have both high bandwidth and high latency, then you run into TCP window scaling issues.
Snapvault uses a 2mb TCP window by default I think, which is also the max it can be. In my case, I want 4mb or higher.
