[gdal-dev] why ogr oracle connection is so slow?

[G. Allegri]

In this period I'm working intensively with Oracle Spatial (on Windows
XP), and I've had the occasion to use it from many perspectives:
through Gvsig with its jdbc-based connector, ArcGis with the
Interoperability Tools, etc.
When I've decided to test the ogr driver I've seen it's times slower
then any other solution. I see it uses the C api (oci.h), but I'm not
capable to debug it to find the bottleneck...

Does anyone can shed light on this?
thanks,
giovanni
