[Cbc] Slow CBC sample example

[Matěj Týč]

Hello,
when I successfully build CBC, I also get an executable (that one called
cbc), that, among other things, accepts MPS files and solves them.

I can also build an example application that does the same things,
according the documentation:

http://www.coin-or.org/Cbc/ch02s02.html

The problem is that the same MPS file gets solved much faster using the
compiled (and somewhat more complicated :-) executable, whereas it
writes a lot of output (even if I try to reduce it) and takes longer
when using the code from the example.

Any ideas?
Regards,
Matej
