I'm using the C++ API of cplex and solve some MIP problems in sequence. When I try to use the method IloModel.end() it takes a long long time. My problem is really big, but I don't undesrtande why it take a long time to end a element. Is there a good way to do this?

If the model you want to end is the model extracted to the IloCplex object, you are better off first ending your IloCplex object before ending the model.
Otherwise, Concert will instruct IloCplex to remove all individual extractables in that model individually, which requires a lot of bookkeeping work.

Hope this helps,
