Description (last modified by )
Versions 2.0+ included a change in the distance code that results in repetitive calculation of the geocentric bounds of objects during distance calcs. This can cause much longer return times. See #1976, comment 7.

Fix committed to 2.0 branch (r10530) and trunk (r10531). 1.5 branch was already fast. Turns out the fix for #1976 made even 1.5 almost 10 times faster.
