It sounds like you are describing a bug.  I can't think of a single
reason why READE should not perform nearly as well as READ, other than
the overhead of the key comparisons.  

How badly does it perform, in comparison to a READ? 

If it's not been implemented properly by IBM than we should file a bug
report.  Has anyone filed a PMR on this matter?
