Callbacks in Cplex

I will try to use LazyConstraintCallback to implement a Branch and Cut algorithm with CPLEX, but when I implemented and run this algorithm, it is very slow if I compare with version that don’t use callbacks in Cplex. It is because ControlCallback(LazyConstraintCallback is a ControlCallback) switch Cplex to sequential mode by default and turn off dynamic search. I write this post, because I don’t find this information in Cplex’s documentation, I only found this information in this technical forum.
