[R] R and C++ compared with only C++

My computer is a pentium 4 running at 2.4 GHz.
My R is 1.7.1

I have written a program in R that calls C++. The program spends most of the
time in C++ ( > 90% ). R basically deals with output and input.
How slower can this be compared with the program I would get from rewriting
everything in C++?

Thank you.
