Mail routing btween Source and Target

QMM does not handle the routing - you have to setup your Connectors in Exchange to support the routing of these namespaces.

I have needed connectors in place. I need to understand the mail flow since I have the source Exchange  located a different geo location than my target Exchange. The existing mail flow is very slow. I was wondering is setting up an additional target server and creating a new dag (target Exchange) in the same city the the source is could fix my slowness issues. 

If the mail routing is not done thru my qmm that means the above idea could work.

There is no archiving approved, AV is there but there are exclusions in place. AV specs: win 2012 r2, RAM 8GB, 4 cores, cpu utilization ~30%

win 2012 r2, RAM 8GB, 4 cores, cpu utilization -30% = Agent Host Server?  

Also find out concerning the Riverbeds

correct. The problem is the traffic routing. I thought that adding a target EX node in  VAN could have resolved the problem

So let me rephrase, your in Site A (Src Exchange Org) syncing to Site A (Trg Exchange Org), correct?

yes 

How much is the Agent syncing per hr per MBX?

Well, it depends on mailbox size. 12gb / 50k items it takes a day, maybe less than that

Personally 1GB hr sounds about right.  24hrs = 24GB.  So, collection A, using Agent (2MBX)=12GB perday, collection B, using Agent(1) (2MBX)=12GB perday.  Have you tried to put only 1 MBX in a collection, and see what it gives you after 24hrs?  If I'm wrong someone else chime in and correct me please.

So this thread started with a question on message routing, and then it went down a rabbit hole of performance. I am guess that we are talking about Migration performance? I assume yes based on the rest of the messages in this thread.. If this was the initial topic. Then "SOURCE <--QMMEX--> TARGET" is how data is moved from source to agent to target. 

Please define you why you think it is slow? 

To sync 100GB of mail my QMM needed over one week. it's subjective but I thought that's slow That was the reason of creating this thread. I started this thread from asking about mail routing to figure out if creating an additional target Exchange server in the datacenter where the source Exchange is hosted from would help with the sync slowness I have been experiencing. 

I also forgot to mention that the total mail size to sync is 4TB. That's a lot of data
