I see the code:
CPLErr GDALSimpleSURF::ConvertRGBToLuminosity
const double forRed = 0.21;
const double forGreen = 0.72;
const double forBlue = 0.07;
question:
if you have a sensor with more than this three channels
probably it will not work you need to have an RGB image.
how about have

Jimmy,
Seems we can get the significant improvement by using bulk inserts then.
You may submit a ticket to keep this enhancements in scope.
Some of the guys used the driver successfully by using FreeTDS on Linux.

Thanks for the answers guys.
What you're saying concurs with what I was experiencing, and I believe, what I
was seeing with the SQL Server Management profiler.
Also, I don't know if inserting with something else than WKT would actually
improve the performance because my test, bulk inserts done
