Remember that aggragate rates are the result of dividing the total
amount of data transferred by the total amount of time from beginning of
the client session to the end. If the client spends a long time scanning
its directory structure before beginning the actual movement of data,
this will skew the aggregate rate results. If you have very long delays
between session start and actual data transfer, and it is a Windows
client, consider using the journaling service.

Also remember that, IIRC, Linux OSs are locked down to handling data in
4K blocks, which greatly restricts the amount data that can flow through
the bus.

What are the actual network data transfer rates (ANE4963I) for your
clients?
