I have installed CPLEX v12.4 and v12.3 and I am running ILOG.CPLEX.dll and ILOG.Concert.dll in my C# code. I had been able to solve a specific problem very fast, in less than five seconds, but, now the same problem takes forever to be solved . The configurations have remained the same.
Would you please help me about this issue?

Please some more information. For example, post the CPLEX output of the fast run and the slow run.
Also, check whether the issue involves the C# code or something else by exporting a SAV file of the
model and running it in interactive CPLEX and also the MIPex2 or LPex2 C# example program that comes
with the distribution. By doing those tests, you will probably be able to narrow down the source
of the problem.
