[Gdal-dev] OGR Shape file Index usage

[Sheykhet, Rostic]

Hi All,

I am trying to use OGR to access a rather large (~90M) shape file with about 215,000 polygons. I am using a spatial filter in my execute call.  The result set is about 3,000 objects but it takes about 20 seconds to execute on a pretty fast machine.  Does OGR use the index file for this query? Is there something else that I can do to speed this up?

Thanks a lot,

Rostic
