Well, of course it is 20 times slower, but looks much much better and
logical.

Add one more test:

    fld = table1.getFieldXtra("f1").
    
    loop 
    {
       fld.getName2()
    }


I think in this case we can get much better results!
The same is true for REALbasic for example.

It is common RULE: 
    if move from loop something then loop will be faster.
    
So test and give us results.


-------------
Also why you use such names?

    getTableXtra() ?

This should be like in realbasic

    gDB.Table("T").Field("f") = 5
