BDE 5.0 SQL on Paradox tables so slow in comparisont to BDE 2.52

Why is opening TQuery on 32 bit BDE so slow in comparison with 16 BIT BDE ?
I have run same TQuery on both BDE and have result of 4 second on 16 bit
and 55 seconds on 32 bit.
What should I do to improve speed on 32 bit ?

I have same BDE configuration and no local share.

Thanx  Marko
