I have seen some additional things. In the first case, without the
POS-attribute, there are nearly 7000 rows in the buffer. This is the behaviour
as expected, the locate-method walks through the buffer until it has found the
record. In this case, the record is the last one, so it has to fetch all records
into the buffer.
But in the second case, with the POS-attribute, there are only 12 rows in the
buffer. Can anybody explain me, how the locate-method has found the record so
fast ?
