P/Invoke vs. C++

575 Views

I have a VB.NET front end which repeatedly calls the Fortran DLL.

Right now I'm using the P/Invoke. What I'm considering though is to re-write that piece of code in C++. I'm passing 3 strings (about 100 chars), 4 int's and a real. Will I see better performance if I do the C++ re-write?
