>When I open the first IBOTable component is very slow. What a problem ?

We need more information. How slow is very slow? What version of
Interbase/Firebird/IBO/Delphi? What operating system? Where do you open
your IBOTable?

The only guess I can come up, is that Windows XP does not like files named
.gdb. Change to .fdb and your problems disappear.
