I really don't know why you are getting a so big diference of
performance, unless the configuration of the TIB_ comps you are using
are diferent from the TIBO you had before (did you check this?).

Of course there is a bit of performance loss with TIBO due to the
added TDataset layer, but I'm sure it would not be responsable for 30%
of performance loss.

Also you cannot compare the performance of a buffered dataset like
TIBOQuery (or even TIB_Query) with unbuffered comps like TIB_Cursor
or TIB_DSQL.
