I wonder what exactly these tests are supposed to mesure ? A lot of them 
are related to string concatenation speed, which I think is one of the 
big changes in FP9. But depending on applications, it's rarely the place 
where performance matters the most. This is a neverending subject to 
debate :)

Maybe measuring some of small operations such as function calls, integer 
calculus, array access... would be more meaningful ? So everybody can 
choose the tests depending on its own application speed issues.

Best,
Nicolas
