When I change the programm to run inside a procedure (because this would
be the more realistic scenario) the performance decreases about 15% -
160ms in global vs 185ms inside procedure.
Using Florian's suggestion, performance outside and inside a procedure
doesn't change that much:
Main program:
[colla@probookcolla SandBox]$ for foo in 0 1 2 3 4 5 6 7 8 9; do
./HappyTickets_florian; done;

Inside a procedure:
