Try to determine slowest query:

- "SELECT ... FROM AFDELING A INNER JOIN STAMDATA_PRG_EXT ..."
or
- "select v509Index from VAREFRVSTR_DETAIL ..."
or
- "Insert into VareFrvStr_Detail ..."


Problem can be with indexes - check whether all indexes exists in new DB (after restore).
Also check your INSERT triggers on VAREFRVSTR_DETAIL (if any).
