Just thought of a very simple test you could run, Michael. Is the plan 
identical for the following query on the old and new server?

select *
from rdb$database
where not exists(
select v509Index
from VAREFRVSTR_DETAIL
where VarePlu_ID=:PVarePlu_ID and
       Afdeling_ID=:AfdNr and
       Farve_Navn=:PFarve_Navn and
       Stoerrelse_Navn=:PStoerrelse_Navn and
       Laengde_Navn=:PLaengde_Navn)

Set
