Why is ExtractByPolygon much slower than Clip?

Question asked by JerryGarcia on Oct 2, 2014

I have same input DEM in a FGDB with a polygon for clip and the same polygon in a feature class for ExtractByPolygon. 

 

Clip finishes in 4 seconds while ExtractByPolygon cranks and cranks...  CPU 100 percent.  It has never finished.

 

I can get ExtractByPolygon to successfully finish with a smaller DEM.

 

Thanks!
