The deal with the dhrystone change is simple :

in 1.1 and lower, HZ was 60, which is fairly normal for *nix systems.
With 1.1.5.1 it was changed to 128 (as told to me by newton@cleese).

As previously reported, some versions of Dhrystone assume HZ is 60, others
make no assumption and require you to specify a value.

Dhrystone 2.1 allows you to do this by specifying a definition of HZ when
you compile, ie -DHZ=60 or -DHZ=128 as appropriate.

Application speed does not appear to have changed significantly between the 
two versions 8).
