Hi,

38 MB/s is not out-of-line(see previous post). Nor do I believe that there are 
there any instances where the statistics are incorrect. You just need to know 
how they are being calculated. See my previous post 'Network data transfer rate 
 & aggregate data transfer rate'. It is almost a perfect example, but explains 
the numbers quite well I hope.

The transfer of the 29 objects that were backed up.  The rest of the time 
was spent getting info from server and sorting though files on client
to decide what needed backing up, and some other overhead stuff.
That's the ideal explanation.

As I look further I see you transferred 1.7GB in 47 secs.  Is that possible
with your network?  There have been some instances (versions) where
these statistics were not correct.  Also if you have multiple backup
sessions to one client it can give incorrect results.

Can someone expound on what exactly DATA TRANSFER TIME specifies.  I've read 
the definition in the manual and it's still not clear to me.  In the below 
example, exactly what took 47.07 seconds?  thx.
