Sorry, I am taking my words back. Have a look again at the times reported
Data transfer time: 8 261.61 sec
Elapsed processing time: 01:25:00
This 8261 seconds is definitely much more than 1h25m (5100s) and one of the
times is erroneous. Divided by wrong value you're getting one of the rates
wrong.

If your network capacity "greatly exceeds the clients ability to send data"
then your network rate should "greatly exceed" the data read (on the node)
and write (on the server) rate. Consequently aggregate rate has also to be
"greatly exceeded". The only explanation I can find to the numbers you're
seeing is that the speed of the SP Switch is incorrectly counted in MHz not
in MB/s. And later those MHz are converted as usual serial Ethernet in
MB/s. Because SP Switch running at low frequency gives high throughput your
network rate is displayed wrong.

I don't think it is a bug. I think is because my network (SP Switch)
capacity greatly exceeds the clients ability to send data (even though is
an S80). If in effect I'm running 2,3,4,5 backups concurrently.

I don't see how aggregate rate could exceed network rate. Aggregate is
Bytes Transferred divided by Elapsed Time, and Network is Bytes Transferred
divided by Data Transfer Time.... what were those values in the session
where Aggregate was greater than Network? How could Data Transfer Time be
greater than Elapsed Time? Must be a bug!

The network transfer rate is the time is takes to send the file to be
backed up to the TSM server.
The aggregate is the total KB backed up / the total time.
The difference is the processing time. The time to contact the TSM server
and check if the file needs to be backed up.
Interestingly enough, my aggregate usually exceeds the network, I was
asking yesterday if any one else sees this.

Can anybody explain why my Network data transfer rate is so high but my
Aggregate data transfer rate is low !!!!!!!!!!!!
