[Ipopt] C++ version of Ipopt is much slower than Fortran version of Ipopt ?

Interesting remark.

It may be an algorithmic difference rather than compilation issue, and
probably more test problems from various fields should be involved.

What is the difference between the Fortran version and the C++ version?
Currently, there are some features in the Fortran version that are not
implemented in the C++ version.

Is the increase in time due to increased (average) time per iteration
or increased number of iteration or both?

Which optimization flags did you use?
