It is as you say, the problems to solve around the application 
have a bigger impact than the language itself.

On our use cases, a few hundred ms are acceptable as response 
times, so it isn't worth developer time to squeeze every ms out 
of the CPU.

My claim is based on the fact, that on my little enterprise world 
I see C++ being stuffed inside legacy boxes in architecture 
diagrams.

C++ code is equated with CORBA and DCOM components that are still 
somehow kept alive.
