With VFP7 it takes less than a second to update the table.
With VFP8 it takes more than 3 minutes
I compiled the same project with VFP8 and reindexed the database using the
Stonefield SDT tools.
I recompiled the project again with VFP7 and runs, as usual,
with the speed of light.
What might be the problem ?

********* the code *********
* the Temp_curs is a cursor of about 50 records
* the Invhed is a table of a bout 250000 records
* there INVHED table has an index on CODE field

Begin Transaction
m_sys=SYS2015()
SELECT temp_curs
Go Top
Scan 
	M_ CODE= temp_curs.Code
	Update INVHED Set ;
		katpel= m_sys WHERE INVHED.Code=M_CODE
Endscan


If  ! Tableupdate(1, .T., "INVHED")
	=Messagebox(" Problem in updating: INVHED ", 16, oApp.Title)
	Rollback
	Return
ENDIF

End Trans
