Zeoslib Portal

I am porting an existing dbase IV system to firebird\zeos and got some serios speed issues. I've been trying to look into it and now I would like to know this:
how come TZQuery.Post is so slow, and why does it executes so many code when trying to define table name for the update sql? Attached is screenshot of call stack

why does it executes so many code when trying to define table name for the update sql

The code executed is needed to make sure zeoslib knows which database fields are behind the fields modified by the user.
