NO, the driver uses the ALLBASE optimizer to accelerate the ODBC queries.
The ODBC performance is quite remarkable!

Yes, you need ALLBASE G1.17 or higher. With this release the update
statistics command has been enhanced to use 'best case' TPI statistics

efficient, predictable plans. G1.19 of Allbase is currently available
as a patch.
