There is _no_ mistake in the math. There are (most likely) multiple streams
going on. I have asked about this before and think I have it straighten out.
Look at the aggregate and network rates. You probably have 4 streams at 10 MB/s
each, for a total of 40 MB/s.
Try using 'run q_ses_stats' (and q ses) during the backup. It will show any
multiple streams. Look in the SUMMARY table to see the stats after the backup
has run.
This behavior is consistent with what I see for a small number (535) of large
files (in 113 GB). Here's a good example where the aggregate exceeds the
network:

I guess we al know TSM F***s up the math big time. I have seen percetages of
over 150% for pct idle/comm/mediaw in q node output....
