In the class test reset the timer:

thanks a lot ... i totally misused the stopwatch api.
i compiled with:
  dmd -release -O -inline -m64 -oftarget/dmd/structs_vs_classes 
experimental/structs_vs_classes.d
and
  gdc -O3 -inline -o target/gdc/structs_vs_classes 
experimental/structs_vs_classes.d

wich resulted in:
target/dmd/structs_vs_classes
time with struct: 11326 for 1
time with class: 11323 for 1

and
target/gdc/structs_vs_classes
time with struct: 4011 for 1
time with class: 6880 for 1

which is much better than my wrong measurements...

thanks for the answer!!!
