There is something else that ought to be considered before
pursuing this route. While it is certainly possible to get
significant speed improvements using a compiled language like C
or C++ instead of Mathematica, that comes at a cost. You have to
spend your time writing code to do things already built-in to
Mathematica and debug that code. The development time for well
written code will almost surely out weigh the time gained as a
result of performance improvements achieve with C or C++.

My experience with Mathematica has been whenever I had speed
issues simply spending more time thinking about the problem I
wanted to solve and perhaps choosing a better algorithm for the
solution as resolved the speed issue. And time spent thinking
about the problem I want to solve I find to be far more
productive than time spent re-creating some high level function
of Mathematica in C/C++ and debugging C/C++ code.
