[Cbc] Need advices for properly using CBC

[Karl St-Cyr]

Hi,

I'm trying to use CBC to solve my linear problem. After implementing a
version of BigM I manage to find a better solution but the time to solve it
is a bit too high for my needs. This is my first time using CBC and I want
to make sure I'm not doing something wrong or missing a way to speed it up.

You'll find 3 dump examples I have problems with in the link bellow (take
note that 1 problem can be composed of 300+ of theses dumps and would need
to execute all of them in more or less 7 min, some of the dumps are also
taking close to no time).

Thank you for your help
Karl
