Re: Implementing a Speed Tip

DO NOT USE THIS METHOD !!!.

The addOverlays code is obsolete, and completely unsupported. The Maps
API code was changed so it is no longer necessary. When it was
initially written, it provided a significant speed improvement. Since
the API code change, it provides only a 5 to 10% speed improvement, in
my tests today.

addOverlays() will not be portable to version 2 of the API.
