Test6: C++ Ofast = 11.5%  FPC -O2 = 19.0%  FPC NoOpt: 24%
Test8: C++ Ofast = 12.0%  FPC -O2 = 17.0%  FPC NoOpt: 25%
Compiled with FPC 3.3.1 and with a bit of tweaking, I got Test6: 16% and Test8: 17%.  (I may have swapped the two results previously.) The executable is about 15% larger than the 3.0.4 version.

I think I'm fully debugged now. Time to see if I can get some vectorization going...

Hey mate, could you get more performance out and made some more optimizations happen?

The difference is not between the languages, but by the implementation of the compilers.
This is an often made mistake, confusing languages with compilers.
IOW the languages themselves are basically just as fast.

If Europe sells their USA bonds the USD will collapse. Europe can affort that given average state debts. The USA can't affort that. Just an advice...
