Hi Patrik,

It's hard to make sense of this without a bit more detail regarding software used, the problem type, etc.

Sometimes small changes in numerics can make a big difference in how the branches of an MIP problem are explored. But without additional info it is foolish to speculate.

I'm using GLPK in one project and the time taken to compute is longer on a more powerful computer. Does it make any sense to you ? 

I don't have any clues about how to debug it. I would really appreciate tips to diagnose the problem.
