BinaryLink vs ObectPtr

[Olivier]

Hi Ruslan and list,

In my tests to know the advantages of the binary links on objetPtr, I 
made a small bench.
(in doc, the advantages and Inconvenience of the various ways are not 
explained)

DB with BinaryLink:
SELECT * FROM zipcity join street we linkcitystreet where zipcode = 
'75000'

DB with ObjectPtr:
SELECT * FROM zipcity, street where street.zipcityptr=zipcity.recid and 
zipcode = '75000'
( If I does not put "street.zipcityptr=zipcity.recid", there is a CRASH)

BinaryLink is faster of approximately 10 %. It is little.
When Valentina 2 will be optimized, both ways will approximately be so 
fast or binarylink will be even faster?
Later, to use binaryLink will allow more possibilities?

thank you
