[Gluster-users] Gluster on fast and slow networks

This is an edge case scenario, but one that I am worried about.

Say you have 2 storage nodes as a mirror on a 10G network, and you write 
into a client mount also on the 10G network. Then data will be 
replicated by the client via the 10G network to the 2 servers.
If one server out of sync because it was off line, then any changes 
would be replicated by the client on the first read. which on the 10G 
network is not a problem.

I add more clients that are on a 1G network.
Now if one of the servers is out of sync and the first read is on a 1G 
client then the data would be replicated via the 1G client. This would 
saturate the 1G link on the client and seriously effect its performance.

Is there a work around/solution for this problem?
