Interesting.
Can you post your gdalinfo report with "-mdd oracle" option?
What are the versions your are running (GDAL,Oracle)?
Older version of the driver used to run a new query every time you change
levels.

yep I did... and the weir thing is that generating the images from "far
away" zoom under 12... it performs very well... not sure why it doesn't
in the levels 13-17.... for that reason I was trying to find the SQL
queries....

Hi All
I am using MapServer + GDAL to render GeoRasters and I am having
very poor performance reading GeoRasters at a high zoom level...
over 13... it would take even 20 seconds per tile...
Did you generate pyramids?
Is it possible to log the GDAL queries that MapServer is doing?
(and the SQL queries that GDAL is doing ?)
thanks
