Replication over WAN is very slow.
We are doing a WAN Replication from Cluster to Cluster.We are replicating Exchange database of size 300 gb.The WAN link of customer is 10 mbps.
We are facing two problems:-
1)Synchronization over WAN is very slow,around 768 kbps & peak is 2 mbps.As per the customer it is a open link.
2)The kernel cache of the Source server goes on increasing rapidly & after touching 100% the Synchroniztion stops. Then we have to delete the data directory & synchronization has to be started once again on all databases.
Can anybody help me.

In 10mbps, it might be not suitable for your requirement.
If you wants to solve it, more than 100mbps is necessary.
It overflows because transfer rate is low.
The link of 10mbps might be a cause.

Please try "Attribute Compare Only"
Perhaps, synchronous time can be shortened.
