I understand you to mean that using COM declarations in C# and C++ is the faster way to
operate compared to declaring C API's in C# and calling them.  If not, please correct me.

I prefer writing in C#, but it isn't possible to go completely to managed code.  As speed is
an issue, perhaps I ought to migrate code in the other direction.  I would migrate some code
across the boundary in one direction or the other, if I had a good understanding of the
costs of crossing that barrier, and knew that it was significant.  If anyone can direct me
in obtaining this understanding, please speak up.
