LM25085: Low measured efficiency

Part Number: LM25085
Other Parts Discussed in Thread: LM27403, LM25145

Hi, we are using a the LM25085 for the 3p3 supply in one of our designs and I'm getting about 86% peak efficiency, I'd like to do better.  this is the measured efficiency of the design:

this is how it's implemented:

The X's over the test points are so they don't get included in the exported BOM, 

Previous designs using this controller have had measured efficiency in the low 90% range, any suggestions on how to get this design into the same range?

Thanks
