Can anyone point to or give an explanation of what this AWR report statistic 
means and/or where it comes from please?

We just moved an OLTP database from 11.1 to 11.2 and my numbers in that 
statistic have decreased dramatically ( down to 1 MB per second ).

Parses per second also dropped dramatically.

The change in the database server ( 11.2.0.3.4 from 11.1.0.7.12 ) also has 
additional memory in the SGA and PGA.  This change was made in conjunction with 
an application server upgrade ( went from 10.2.0.4 client to 11.2.0.3 client ).

The changes are all extremely positive just trying to sort out why so much 
better!
