Exchange Mailbox Moves

Is there a throttling policy for exchange when it comes to mailbox moves. I'm moving mailboxes from 1 exchange org to another, but this is all a local site with the same SAN storage and the same subnet. We basically stood up AD and exchange in the enviroment so that the moves would stall local and not traverse internet. SAN is 10 GB links and 10K disks. I'm not sure why so slow and I found the following link:

I'm not sure if that would be the cause. This seems to increase the number of mailboxes you can move at a time but will this increase the actual move speed? Is there throttle policy that affects the speed of moves also? It takes all day to move 4 mailboxes and they are no larger than 2 GB each. Any advise will be great.

There is a limit to move only 4 users concurrent at a time. but about slow movement, I think you must need to check network latency between Mailbox server not at SAN switch. because when you are giving any request to move server it uses LAN rather.

Check network performance are they connected on GBps network or still on Mbps.

They are connected to Gbps networks.  I will check with the network team about this then. I just wanted to be sure that I wasn't missing something on the exchange side. Also whats the highest number i can set the concurrent mailbox moves to in the: MaxActiveMovesPerSourceMDB and MaxActiveMovesPerTargetMDB, and is there a recommended other than 4?

No don't change it, let it be default. but please check network performance during movement.

I hope you have two network interface on DAG network in both Exchange org. which is best practice.
